I have a project to build with stack and it depends on network. When I do stack build, it says
[1 of 1] Compiling Main ( /tmp/stack23678/network-2.6.2.1/Setup.hs, /tmp/stack23678/network-2.6.2.1/.stack-work/dist/i386-linux/Cabal-1.22.5.0/setup/Main.o )

Configuring network-2.6.2.1...
...
checking whether the C compiler works... no
configure: error: in `/tmp/stack23678/network-2.6.2.1':
configure: error: C compiler cannot create executables
See `config.log' for more details
Sure, I'd love to. But where is this config.log? Or how can I re-create it?
Just cabal install network (without stack) works fine but how could stack build use this?
In order to get better information here, you can make sure all generated files are saved by manually building network:
stack unpack network-2.6.2.1
cd network-2.6.2.1
stack init
stack build
I think C compiler cannot create executables means you don't have a working C compiler installed.
config.log is generated by the configure command, and I don't think stack saves that. stack does save other logging output in
~/.stack/global-project/.stack-work/logs/...
It's the same as what was emitted to your terminal, so it may not help.
