I'm trying to compile vim8.2 on CentOS 8.4.
When executing ./configure --with-features=huge --enable-multibyte --enable-python3interp --enable-perlinterp --enable-luainterp --enable-cscope --enable-fail-if-missing --with-python3-command=/usr/bin/python3.8 --with-tlib=ncurses, it renders the error:
checking for linking with ncurses library... OK
checking for tgetent()... configure: error: NOT FOUND!
You need to install a terminal library; for example ncurses.
Or specify the name of the library with --with-tlib.
I've installed ncurses with its respective libraries, ncurses ncurses-devel ncurses-libs ncurses-compat-libs ncurses-c++-libs.
The question lies where to find the ncurses libraries, so that it can be pointed to
--with-tlib. Thanks in advance.
Vim's a termcap application, and uses only the low-level termcap functions from the ncurses libraries. CentOS packages that as two libraries (ncurses or ncursesw, and tinfo). That's been a configure-option of ncurses since 1998, and is used by packagers who want to minimize the size of installers, etc.
If it used pkg-config, vim's configure script would do the right thing with this output:
% pkg-config --libs ncurses
-lncurses -ltinfo
For "tlib", you'll need the "tinfo" library, e.g.,
--with-tlib=tinfo
However, on some systems, there can be additional problems. In any case, the actual problem is reported in the config.log file. On inspecting that, most developers find the solution obvious.
(This was asked previously without the answer providing insight).

I have been attempting to link a MACHO formatted object file on Linux, but I have failed miserably. So far, I have created the object file by running:
nasm -fmacho -o machoh.o hello.o
I have tried linking using:
clang --target=x86_64-apple-darwin machoh.o
but that failed. I have attempted using GCC, LD, and other linkers but I have still failed miserably. Are there any ideas on how I could solve my problem?
Thank you very much.
The most accessible solution would be lld, the LLVM linker.
lld does not ship with clang, but is a separate package.
sudo apt install lld
If you installed a version of clang that isn't the default (e.g. clang-12 explicitly), then you should use the same version for lld (i.e. lld-12).
Get a MacOS SDK from somewhere. This GitHub repo archives them.
If you're uncomfortable using the above, the "legitimate" way of obtaining it without a Mac would be:
Create an Apple ID
Go to https://developer.apple.com/download/all/
Download the "Command Line Tools for Xcode <version>"
Mount or extract the dmg
Extract the XAR package
For each ".pkg" folder inside, run pbzx <Payload | cpio -i
Find the Library/Developer/CommandLineTools/SDKs/MacOSX.sdk inside.
Feed both of the above to clang:
clang --target=x86_64-apple-darwin -fuse-ld=lld --sysroot=path/to/MacOSX.sdk machoh.o
I have tried linking using: clang --target=x86_64-apple-darwin machoh.o
but that failed.
Failed how? Details matter.
Anyway, there are 3 commonly used linkers on Linux: BFD-ld, Gold, and (newest) LLD.
Of these, Gold is an ELF-only linker, and will not work for Mach-O.
BFD-ld is only configured to support a few emulations (use ld --help to see which ones) in my distribution. BFD does appear to support Mach-O, so it's probably possible to build a Linux BFD-ld cross-linker with such support.
LLD should support Mach-O out of the box, but you are probably not using LLD.
So your first step should be to figure out which linker clang --target=x86_64-apple-darwin ... uses, and then make it use the one which does support Mach-O.
I'm trying to install this project: https://github.com/drufat/triangle. Unfortunatly, I get the following error:
error: Cygwin gcc cannot be used with --compiler=mingw32
I'm using the lastest version of gcc for Cygwin on Windows 7 64 bit and I'm trying to install that project for python 3.7.1. It's seems to come from my distutil configuration. My distutils.cfg file contains:
[build]
compiler=mingw32
I tried that solution but it doens't helped:

The gcc options to build for MinGW64 is no longer supported by the regular cygqin compiler gcc, aka x86_64-pc-cygwin-gcc. Instead, you should also install the mingw64-x86_64-gcc-core package which provides the GCC for Win64 toolchain (C, OpenMP). This will also install other packages (through dependencies) which provide compatible binutils, headers, libraries, and runtime.
In your Makefile or compiler command line, replace gcc with x86_64-w64-mingw32-gcc. This will allow you to compile and link executables which do not depend on the cygwin1.dll.
A similar problem occured. I fixed it by changing mingw32 by gcc like #phd said.
Working with embedded C-projects. There are libraries, include files and so on - for micro controllers. No need for me to use GCC for a host machine and OS (Linux Mint 64 bit). As a rule...
But now I'm trying to compile mspdebug project from a Github - with a GCC of course. And I get an error at the very begin of make:
mspdebug$ make
cc -DUSE_READLINE -O1 -Wall -Wno-char-subscripts -ggdb -I. -Isimio -Iformats -Itransport -Idrivers -Iutil -Iui -DLIB_DIR=\"/usr/local/lib/\" -o util/btree.o -c util/btree.c
util/btree.c:19:20: fatal error: assert.h: No such file or directory
#include <assert.h>
^
compilation terminated.
I search for the includes in all possible paths (I've got the list of them via gcc -v command) - there are no assert.h file, as well, as stdio.h and so on. Except virtual box directories there is only one place (where GCC does not search includes): /usr/lib/syslinux/com32/include
AFAIK, all standard libs and includes are installed with the GCC. So I try to reinstall GCC (4.8.4) - nothing changes.
What is the normal way to give GCC all standard environment it needs?
Thanks to the right direction set by Sam Varshavchik I found the info in the stackoverflow. So I did the following:
1) installed build-essential:
sudo apt-get install build-essential
2) installed libusb (since my try to build the package revealed the absence of usb.h):
sudo apt-get install libusb-dev
And it is OK! The mspdebug (v.023) is compiled and successfully tested!
So, Linux Mint 17.2 (at least) requires installing some libs to a GCC, the most basic is build-essential.
assert.h is not part of gcc, it's a part of glibc.
Most likely, your Linux distribution puts the system headers into a separate package that you need to install.
Fedora, for examples, puts the header files in the glibc-headers package. However, you can't be using Fedora, because Fedora's gcc package has a dependency on glibc-headers, to make sure that it gets pulled in.
Whatever Linux distribution you're using, you need to research which distribution package will install the system header files you need to build stuff with.
I am trying to build Guile 1.8.8 from source. I am stuck at the point where the build system is looking for libtool. I have installed it in a non-standard location.
I have already built Guile 2.0.11. In 2.0.11 build system, there is an explicit flag to configure --with-libltdl-prefix, which I think tells the build system where libtool is installed.
For Guile 1.8.8, I have Libtool installed in a non-standard location. How do I tell the build system where it is installed?
I am specifically getting error messages like:
libguile/Makefile.am:40: Libtool library used but `LIBTOOL' is undefined
libguile/Makefile.am:40: The usual way to define `LIBTOOL' is to add `LT_INIT'
I think in general this is a question regarding one or more of the autotools and how the build system finds programs / headers / libraries in non-standard locations.
This link is informative: How to point autoconf/automake to non-standard packages
Find the directory where *.m4 exists, which corresponds to libtool, or package which is in non-standard location.
export ACLOCAL_PATH=/path/to/m4/file
cd /path/to/configure.[in,ac]
autoreconf -if
./configure
I am trying to compile a library using android-ndk-r5 standalone toolchain and autotools. When doing a ./configure, it fails with:
$ ./configure --host=arm-linux-androideabi
...snip...
checking host system type... Invalid configuration `arm-linux-androideabi': system `androideabi' not recognized
configure: error: /bin/sh ./config.sub arm-linux-androideabi failed
Explicitly setting CC and CXX does not work either (configure says to use --host).
The NDK docs and various materials online seems to indicate that using the standalone toolchain in this manner should be possible. What is wrong here? and how can I resolve it? (besides simply ditching autoconf and going back to Android.mk)
You might need a newer config.sub and config.guess, 2010-05-20 or later.
You can get the newer config.sub and config.guess from here
I took the newest from both, but that lead to errors, so I took the mentioned ones of Peter Eisentraut's date.
You can also grab config.sub and config.guess from the Ubuntu autotools-dev package:
sudo apt-get install autotools-dev
cp /usr/share/misc/config.{sub,guess} .
