Re: [igraph] igraph compilation with Cygwin

[Josep Bau]

Hi,
Thanks a lot. I run the 'make' and 'make install' with no problems.
Sorry to bother but I'm trying now to run the test file in the reference manual (erdos renyi game) but I get errors.
I copied the libigraph.a file to the main directory that also contains igraph.h and igraph_test.c and typed this on cygwin:

$ gcc igraph_test.c -I./src/ -L./src -o igraph_test

I get this:

/cygdrive/c/Users/Compaq/AppData/Local/Temp/ccOpNk3D.o:igraph_test.c:(.text+0x60
): undefined reference to `_igraph_erdos_renyi_game'
/cygdrive/c/Users/Compaq/AppData/Local/Temp/ccOpNk3D.o:igraph_test.c:(.text+0x9a
): undefined reference to `_igraph_diameter'
/cygdrive/c/Users/Compaq/AppData/Local/Temp/ccOpNk3D.o:igraph_test.c:(.text+0xb8
): undefined reference to `_igraph_destroy'
collect2: ld returned 1 exit status

Yes, this seems to be a known bug:
https://bugs.launchpad.net/igraph/+bug/380622

A workaround is to install the GMP package as well, I think it is
included in cygwin, do ./configure again, it should find GMP and then
the compilation should be fine.

Best,
Gabor
