x86_64 build log

Re-emerging cross-x86_64-w64-mingw32/mingw64-runtime with the "librarires" useflag fails at the configure step with

```
checking for x86_64-w64-mingw32-gcc... x86_64-w64-mingw32-gcc
checking whether the C compiler works... no
configure: error: in `/var/tmp/portage/cross-x86_64-w64-mingw32/mingw64-runtime-9.0.0/work/mingw-w64-v9.0.0/mingw-w64-libraries/libmangle':
configure: error: C compiler cannot create executables
See `config.log' for more details
```

same happens the i686 version

Any ideas ?

Thanks!

This bug report is probably the reason behind bug https://bugs.gentoo.org/833207

[Comment 4 James Le Cuirot 2022-02-13 21:21:30 UTC]

IIRC you have to build it without libraries first, and then enable after that.

I do have it installed without libraries, but then it fails to emerge, as you can see in the emerge -pqv attachment. I don't know why it's like this

Initially I use this script to initially build the cross toolchain, maybe I am doing something wrong in that:

```
#!/bin/bash

```

Okay something changed and I need to enable more flags than "libraries", mingw64-runtime needs "libraries idl tools", this code snippet works

```
#!/bin/bash

echo "######################################"
echo "Generating x86_64-w64-mingw32"
echo "######################################"

crossdev --target cross-x86_64-w64-mingw32
crossdev --lenv 'USE="libraries"' \
--genv 'EXTRA_ECONF="--enable-threads=posix"' \
--init-target --target cross-x86_64-w64-mingw32
env USE="libraries idl tools" emerge --oneshot cross-x86_64-w64-mingw32/mingw64-runtime
env USE="libraries" emerge --oneshot cross-x86_64-w64-mingw32/gcc

# i686

echo "######################################"
echo "Generating i686-w64-mingw32"
echo "######################################"

crossdev --target cross-i686-w64-mingw32
crossdev --lenv 'USE="libraries"' \
--genv 'EXTRA_ECONF="--enable-threads=posix --disable-sjlj-exceptions --with-dwarf2"' \
--init-target --target cross-i686-w64-mingw32
env USE="libraries idl tools" emerge --oneshot cross-i686-w64-mingw32/mingw64-runtime
env USE="libraries" emerge --oneshot cross-i686-w64-mingw32/gcc
```
