ld.exe cannot find -lfcgi on windows 10

[Anonymous]

I am trying to get fast cfi working with GnuCOBOL on Windows 10 and seem to be missing fcgi.
When doing cobc -x xxx.c -lfcgi after mocifying the c code to replace stdio.h with fcgi_stdio.h receive the following error:
ld.exe cannot find -lfcgi
Could someone be able to point me to where I can obtain it and where it should be installed.
Thanks,
Dave Lumley

As this information is missing: what version of GnuCOBOL do you use (cobc --info)?

It can't find it, because there is no fastcgi library laying around somewhere.

I have not checked if that works but I guess the following possibly works on a 32bit MinGW like yours [for 64bit at least the config file has to be adjusted]):

• download and unpack fastcgi from https://github.com/FastCGI-Archives/fcgi2/releases/tag/2.4.2
• source the MinGW/GnuCOBOL environment by opening the includedset_env.cmd
• execute the following commands:

pushd X:\path\to\fastcgi\include
copy fcgi_config_x86.h fcgi_config.h
cd ..\libfcgi
gcc -I ..\include -shared -o libfcgi.dll -lws2_32 -Wl,--out-implib,libefcgi.dll.a fcgi_stdio.c fcgiapp.c os_win32.c
:: if the above did not created an error
cd ..
copy include\fcgi_stdio.h  %COB_MAIN_DIR%include\
copy include\fcgiapp.h     %COB_MAIN_DIR%include\
copy libfcgi\libfcgi.dll   %COB_MAIN_DIR%bin\
copy libfcgi\libfcgi.dll.a %COB_MAIN_DIR%lib\

Note: in any case you should not need to post-change the C source, instead let cobc (actually the called gcc) "logically" insert it by use cobc -x program.cob -A '--include fcgi_stdio.h' -lfcgi
