Build error with Haskell GD bindings - haskell

I've installed the GD package (http://hackage.haskell.org/package/gd-3000.4.0) using cabal. When I try to compile the program which uses GD I receive an error:
[mp262554#students:~/jpp/haskell]$ ghc gd.hs

GD package provides bindings to GD library written in C. You need to link the C library to your program. Try --make option of the GHC first:
ghc --make gd.hs
GHC with --make should figure dependencies automatically and link a multi-module program correctly. You can also consider using -l and -L options manually.

Messages like this may indicate that files do in fact need recompiling. Try ghc -fforce-recomp

...lib/crt1.o: In function `_start': (.text+0x18): undefined reference to `main' with IDL6.2

I am trying to build an old program using IDL6.2 in CentOS7, which was originally built for RHEL3 and runs in RHEL5.
However, when I try to make it in CentOS7, I get the error bellow.
May that be an compatibility problem? How can I solve it?
Thanks!
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib/crt1.o: In function `_start':

Found the root of the problem! Incompatibility of Automake between the versions 1.9 (in RHEL5) and 1.13 in (CentOS7).

Unable to runhaskell my wxHaskell program that works in GHCI

I am trying to create a HelloWorld.exe on Windows 7 that demonstrates a very simple wxHaskell program I have found online. The code is below:
module HelloWorldWX where
import Graphics.UI.WX
main :: IO ()
main
= start hello
hello :: IO ()
hello = do
f <- frame [text := "Hello!"]
quit <- button f [text := "Quit", on command := close f]
set f [layout := widget quit]
in a file called HelloWorldWX.hs. I downloaded the binary distribution of wxHaskell (wxInstall-Achelanne-64-0.1). After running Install.bat I noticed it used Cabal to set up a new package location where it installed wx-0.92.0.1 and all of its depedencies. The first time it ran it failed for some non-specified reason. I ran ghc-pkg list and found all of the packages were listed in the new cabal package location. I decided to unregister all of the packages and try again. This second time it was successful and prompted me to include the following directories in my search path which I did:
C:\Users...\Downloads\wxInstall-Achelanne-64-0.1\DLLs;C:\Users...\Downloads\wxInstall-Achelanne-64-0.1\wxWidgets\lib\gcc_dll
At this point when I loaded HelloWorldWX.hs into GHCI and ran main, I got the window frame with the Quit button like I expect.
I then compiled the .hs file into a .o file. I then attempted to create an executable with the following command:
ghc -v -o HelloWorldWX HelloWorldWX.o

I am not really sure why it is having problems finding these references.
I tried executing then with
runhaskell HelloWorldWX.hs
and received the following error popup from ghc:
The Verbose flag being set here gives a bunch of information that doesn't really elaborate on any specific problems.
I am running Haskell GHC 7.10.3 full package from Windows Installer to a local Users directory. I do not have Local Administrator privileges on this workstation but I could try on another machine.
Any clues? I imagine the first failed install of wxHaskell has corrupted something or I am running into a privilege issue.
I figured out what the problem was. I forgot that for GHC to create an executable that you need to explicitly specify Cabal packages that you wish to include. Commenter Tomasz Lewowski was partially correct. The -L option for linking libraries was required by gcc, however the ghc application intelligently adds ALL the required library paths for a given Cabal package by using the -package option.
The second part of making this work was that I needed to compile the .o file specifying -main-is for the main method. I wrote up the simple batch file and got it working.
ghc -v -main-is HelloWorld.main HelloWorld.hs
ghc -v -o HelloWorld HelloWorld.o -package strict-0.3.2 -package wx-0.92.2.0 -package wxc-0.92.2.0 -package wxcore-0.92.2.0 -package wxdirect-0.92.2.0
This created the Windows executable just fine and it works like a charm.

Installing pciutils on Cygwin and makefile error

I want to run a project that communicates with a USB device using libusb. I already have it on Linux, and it works great there, so I want to run it on Windows with Cygwin. I installed libusb for Windows and libusb in Cygwin, then tried to compile it. It turns out that you need pciutils, unlike on Linux in which it's really easy to get it. In Cygwin it's a problem.
After overcoming some difficulties I managed to get further with my purpose of compiling pciutil in the Cygwin environment. I follwed these steps:
Download winio package for Windows and went to Winio\Binaries and copied winio32.dll and winio32.sys to the pciutil directory.
Copy config.h/mk from ../win32 to ../lib
Go to ..\lib\i386-io-winodws.h and change line 39 to "lib = LoadLibrary("WinIo32.dll");"
$ make
The make step didn't work. It showed me a makefile error, so I tried to play with it without any luck.
I got this error:

Since you're using a 32-bit version of Windows you can use the Cygwin port of pciutils. The files in the win32 subdirectory are actually for the MinGW port, and that's why you get the link errors.
The first thing you should do unpack the source files to a new directory so you can start from fresh. Your changes and modifications aren't necessary to compile it using Cygwin. Be sure not to copy any of the files in the win32 directory this time, they're not needed. Also don't copy the winio32 files, you don't need them either. Don't make any changes to any of the files.
The next thing to do is to install the ioperm package using Cygwin's setup-x86.exe. Type ioperm in the search box to quickly find it amongst all the other packages. Once it's been installed run ioperm -i from the Cygwin prompt to install the driver that allows applications to do direct I/O.
Next change directory to where you unpacked the fresh copy of pciutils and run the following command from the Cygwin shell:
make HOST=i386-pc-cygwin
That should be all you need to do to create the library and utilities.

Error "collect2: error: ld returned 1 exit status" shows while compiling vim (Versin>=7.4.399) from Cygwin

I've tired to maintenance the latest VIM/GVIM for windows, here is my OpenSource project.
However, I found the compile always failed by cygwin since the vim version higher than v7.4.399 (including v7.4.399).
Version less than v7.4.399 can be compiled with the same command successfully!

I checked the difference between v7-4-398 and v7-4-399, and found there something updated with encryption. Then I added the libs and other stuff about crypt in cygwin as below, but the compile still CANNOT work....
What should I do can compile the higher version vim ?
Environments:
Cygwin version: Latest setup-x86_64.exe, mintty 1.2-beta1 (x86_64-pc-cygwin)
Have you tried compiling with all the patches that are currently available. I think Bram Moolenaar (Maintainer for vim) forgot to add some of the files in one of the patches and one of the later one fixes that. If not post to vim_dev#vim.org
This was also reported to at https://groups.google.com/forum/#!topic/vim_dev/D8FyRd0EwlE.
Patch 7.4.401 should fix it https://groups.google.com/forum/#!topic/vim_dev/q0dbl0_9k9U
Got this issue again on CentOS 7, Python 2.7.10, 64bit.
According to this answer, this issue has been fixed;
export vi_cv_path_python_plibs="-L/<python_config_path> ..."
For example in my situation:
export vi_cv_path_python_plibs="-L/usr/local/lib/python2.7/config ..."
Compile command:
$ ./configure --prefix=$HOME/.marslo/myprograms/vim74 --enable-pythoninterp --with-python-config-dir=/usr/local/lib/python2.7/config --with-features=huge --disable-smack --enable-cscope --with-tlib=ncurses --with-compiledby=marslo#china
$ cd src && make first
$ cd .. && make
$ make install
You can disable sodium library in ./configure such as :
./configure -disable-libsodium

Undefined reference errors when including external library libxml2 in android ndk

I'm trying to use libxml2 with android ndk. When I run the make file, I got errors saying that file 'unicode/ucnv.h' does not exist. I've seen 'unicode/ucnv.h' is included in one of the files and no such header file is present. So I downloaded unicode header files from http://site.icu-project.org/ and placed them in include folder.
Now the previous error is gone but I've got these errors.

I didn't find function ucnv_open_49 in any of the files.
Am I the only one who is facing this problem?
Build unicode library (icu) along with libxml2 and mention in LOCAL_SHARED_LIBRARIES.
That's it!
Are you intending to link libxml2 against ICU (e.g. use it for conversion)? It's optional but currently you have it enabled. With such you'll need ICU to be linked in as well rather static or dynamic. See the libxml2's configure script for options. Some of which are iconv or even no converters if you intend to work with UTF-8 only.
