How to check for a dependency with autoconf? - autoconf

I have a program that is configured with a configure.ac file that crashes with some generic errors if libtool is not installed (unix).
How would I add a "check" for libtool that will provide a description, eg "libtool is not installed so the install failed" or something like that? I've never delved into this type of code before so have no idea
Thanks

use PKG_CHECK_MODULES to ensure libtool is installed.
Here is the documentation for the macro: https://autotools.io/pkgconfig/pkg_check_modules.html

How to obtain debug information (symbols) for gcc OpenMP library?

I have a GCC OpenMp library (libgomp.so) that doesn't contain any symbol, and I need to either install/compile a new library with symbols or obtain debug information for the library. I found something (lib64gomp1-dbg) in the gcc-5 package, but I'm not sure if this is what I want and I don't know how to install it either (I've tried sudo apt-get lib64gompl-dbg, but it didn't work, it threw the error: E: Invalid operation lib64gompl-dbg). So how can I get debug symbols for the library? I'm fresh new to Linux, can somebody give me a hint on how to do that? Thanks a lot!
You need to use
sudo apt install lib64gompl-dbg
(Note the inclusion of the word install.)

Installing GnuCOBOL something missing

Hello Im trying to install GnuCOBOL
in part of configuration I got that message
configure: error: no acceptable ld found in $PATH
if someone can help plz, thank u.
Moving a comment to an answer, for completeness.
You'll need to use Cygwin setup.exe to install binutils, make, gcc, gmp, libgmp-devel, ncurses, libncurses-devel, libdb, libdb-devel, possibly others in the development package group.

Cabal can't find foreign libraries

Recently I was trying to install llvm-general-3.5.1.0 package.. for about a week. Basically I am getting this error: link. My situation is identical. Windows 10, ghc 7.10.2, cabal 1.22.4.0. I installed llvm 3.5.2 from sources with cmake and everything went fine. In llvm/lib directory I have *.lib files (eg. LLVMAnalysis.lib).
But somehow cabal can't see those libraries and gives this frustrating error:
Configuring llvm-general-3.5.1.0...
setup.exe: Missing dependencies on foreign libraries:
* Missing C libraries: LLVMLTO, LLVMObjCARCOpts, LLVMLinker, LLVMipo,

This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
I really want to use this package on my Windows, but nothing seems to work (I tried everything like --extra-lib-dirs and compiled also with MinGW and VS - the same problem).
I can't accept the fact that it won't install. I mean, there must be some way to fix Setup.hs from this cabal package or something. Does anyone have an idea what can be wrong with cabal in this case and how can I try to workaround this? I don't know how exactly cabal works, maybe someone with this knowledge will have an idea? Or maybe there is a way to do this without cabal?
Ok, i've managed to build it and, i think, found the root of the issue.
First, steps to build:
Get the MinGW. My installation of MinGW has gcc 4.8.
Get 32-bit MinGHC.
Compile LLVM 3.5 with MinGW's gcc and install it somewhere.
Copy contents of MinGW installation directory into MinGHC Install
Dir\ghc-7.10.2\mingw, replacing conflict files.
In the command line set your PATH so it has haskell toolset from
MinGHC (i recommend using switch .bat scripts) and llvm-config.exe.
Get the llvm-general package source either using cabal fetch or
downloading via browser from hackage.
Replace cc-options: -std=c++11 line of llvm-general.cabal with
cc-options: -std=gnu++11.
Finally, cabal configure and cabal build should work.
I have been changing my build environment many times, so if this doesn't work for you let me know, i probably forgot something.
Now let's go into details.
What we thought is a bug of cabal is not, actually. The problem is that both stack and MinGHC (and Haskell Platform, i guess) use quite old gcc - 4.6. This gcc has even two defects:
It doesn't support -std=c++11 and LLVM 3.5 can't be built using it.
As a consequence, this gcc can't be used by ghc when compiling
llvm-general, because it can't parse LLVM headers properly.
Even if it could, its linker can't link against LLVM libs compiled by
MinGW using gcc 4.8. This is why cabal was telling you it
couldn't find LLVM libs. I've hacked Setup.hs so that it wouldn't
look for these libs, but pass -lLLVMSomething to linker via -pgml
ghc option. This lead to clear error message:
ld.exe: ignoring libLLVMSupport.a ...
ld.exe: can't find -lLLVMSupport
So, the cabal was actually finding these libs, but was dropping them because they couldn't be linked to.
Ideally, the solution would be to update mingw distribution used by stack/MinGHC. But as a workaround you can just replace old gcc with new one.
Finally, -std=gnu++11 is used because current MinGW release is affected by this bug, which prevents compilation of c++ bits of the package. Whew, that was a long way.

Where is libHSprimitive-0.5.3.0.so

Trying to install MFlow on linux mint. sudo cabal install MFlow gives me this:
Loading package primitive-0.5.3.0 ... : can't load .so/.DLL for: libHSprimitive-0.5.3.0.so (libHSprimitive-0.5.3.0.so: cannot open shared object file: No such file or directory)
Failed to install vector-0.10.9.2
cabal tells me that I do have primitive-0.5.3.0 installed. Any hope of getting this to happen?
Thanks much for any help!
I ran into the exact same issue. So here's some elaboration on the problem.
The comment by user2407038 provided the answer. By default, shared is set to False so shared libraries are not built. This means any libraries that expect to link to the shared library libHSprimitive-*.so would fail to build.
The solution was to reinstall primitive with shared set to True. You can do this either by modifying ~/.cabal/config or by passing an extra argument:
cabal install --reinstall --enable-shared primitive

CMake can't find Curses

I am trying to compile the openlase library from www.marcansoft.com and have been running into problems with CMake. CMake is returning an error stating that it cannot find Curses, and after a lot of looking I am still stumped as to what the issue is. I have checked that I have the various ncurses packages installed but still the error persists. Im not very familiar with CMake but I was able to resolve other dependency issues that arose before this one. The following is the output in terminal.
tom#SILVER:~/dev/openlase$ cmake ./
-- Found JACK
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:70 (MESSAGE):
Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)

Any help would be greatly appreciated.

Here is what fixed my problems on Ubuntu 12.04 x86_64 (64 bit) (Thanks syslogic )
For whatever reason (1:00 am maybe?) setting CURSES_USE_NCURSES TRUE didn't seem to work. So I went with a hack job.
Verified it's installed:
$ sudo apt-get install libncurses5-dev
You will see something to the effect: libncurses5-dev is already the newest version.
So find the library and include.
$ locate libncurses.so
Note location, mine: /usr/lib/x86_64-linux-gnu/libncurses.so
$ locate curses.h
Note location again, mine:
/usr/include
In: <cmake source dir>/Modules/FindCurses.cmake
add at the top, right after the comments
set( CMAKE_INCLUDE_PATH "/usr/include")
set( CMAKE_LIBRARY_PATH "/usr/lib/x86_64-linux-gnu/libncurses.so")
then rinse repeat the build process
./bootstrap
make
sudo make install
ccmake should now be installed.
Your pal,
Another way to fix it is to add these 2 lines to FindCurses.cmake (on top):
set(CURSES_LIBRARY "/opt/lib/libncurses.so")
set(CURSES_INCLUDE_PATH "/opt/include")
Temporarily set CURSES_USE_NCURSES to TRUE to force the use of NCURSES, rather than letting CMake try to find CURSES.
Do you have the corresponding -dev package installed too? On Ubuntu (and probably anything derived from Debian) it is libncurses5-dev. Other systems may use -devel or similar tags.
The compiler is looking for the library headers, and those aren't provided by the standard package. (The headers aren't needed at runtime, only when compiling software, so they make it easy to remove extra useless stuff for systems that aren't going to be doing any software compiling.)
The openlase wiki was not displaying all of the needed packages. Check there wiki pages on github for updated instructions. For curses the missing package was libncurses5-dev sudo apt-get install libncurses5-dev
Temporarily set CURSES_NEED_NCURSES to TRUE to force the use of NCURSES, rather than letting CMake try to find CURSES.
set(CURSES_NEED_NCURSES TRUE)
CURSES_USE_NCURSES is used by FindCurses.cmake internally, so setting that won't help.
