Vcpkg: [pcre] build failure on linux

[illera88]

It's making a bunch of other projects to fail to build like glib

Host Environment

• Compiler: gcc (Debian 8.3.0-6) 8.3.0

To Reproduce
Steps to reproduce the behavior:
./vcpkg install pcre

Hi @illera88
Could you please remove openssl first and then rebuild this? Then send me the log. I cannot reproduce this on my local.

[illera88]

I did delete all the openssl installations I had. Here are all the logs which I checked but I couldn't find anything weird

Btw, I'm running this in a Debian WLS machine.

@Neumann-A Can you please take a look?

Thanks.

[JackBoosY]

@illera88 Please provide the library names in _VCPKG_PATH/packages/pcre_x64-linux/lib_ and _VCPKG_PATH/packages/pcre_x64-linux/debug/lib_.

Thanks.

[illera88]

It seems that the release version libraries have been built fine but not the debug right?

[Neumann-A]

you probably have set(VCPKG_BUILD_TYPE release) set in the triplet? For me it works locally so some info here is missing

[illera88]

Indeed I had set(VCPKG_BUILD_TYPE release) in the triplet and I have verified that without that it compiles fine.

There is still a bug since it should not fail if you just want to build the release version.

Can you add set(VCPKG_BUILD_TYPE release) to your x64-linux.cmake triplet file and verify?

Thanks

[Neumann-A]

@JackBoosY this is a port bug. The pcre port should not install pc files for debug if the buildtype is set to release only.

[JackBoosY]

@Neumann-A I think vcpkg_fixup_pkgconfig should actively handle this situation.

[Neumann-A]

No it is a failure in the port installing files which are not required. As such the failure is correct.
