[Monetdb-developers] Cygwin: implicit declaration of function closesocket
Hi all, a student of ours is trying to compile the current CVS snapshot (the tarball from the website) on Windows using Cygwin. He's getting the error stream.mx:1471:implicit declaration of function closesocket. In the attached config.log, it seems like closesocket could be detected (i.e., successfully linked in). Is there maybe some #include missing in stream.mx to declare closesocket()? The attached config.log, by the way, is full of `gcc: unrecognized option `-no-undefined'' warnings. Is this supposed to be like this?

I cannot find a compiler that does like it: (pegasus:~) fabian% gcc-config -l Using gcc-config info in /ufs/fabian/scratch/programs/gentoo/ [1] x86_64-pc-linux-gnu-3.3.6 [2] x86_64-pc-linux-gnu-3.3.6-hardened [3] x86_64-pc-linux-gnu-3.3.6-hardenednopie [4] x86_64-pc-linux-gnu-3.3.6-hardenednopiessp [5] x86_64-pc-linux-gnu-3.3.6-hardenednossp [6] x86_64-pc-linux-gnu-3.4.6 [7] x86_64-pc-linux-gnu-3.4.6-hardened [8] x86_64-pc-linux-gnu-3.4.6-hardenednopie [9] x86_64-pc-linux-gnu-3.4.6-hardenednopiessp [10] x86_64-pc-linux-gnu-3.4.6-hardenednossp [11] x86_64-pc-linux-gnu-4.1.1 * (pegasus:~) fabian% gcc-config 6 * Switching native-compiler to x86_64-pc-linux-gnu-3.4.6 ...

I'm working on it. closesocket is required for MinGW, but I think not on Cygwin. I have to refine the tests in configure.

Stupid configure. -no-undefined is required as an option to ld so it is added to LDFLAGS. But configure passes it to gcc during testing. (In real life, libtool passes it directly to ld.) -- Sjoerd Mullender
