Having trouble building love from source

[bizziboi]

I pulled the full source tree (megasource+love) yesterday, but when trying to build it (windows. cmake 3.5.0, VS2013 Express) I have a series of errors, specifically in Freetype. Just curious if others are able to build the current depot.

[XxHAMADEHxX]

Could you post the errors you are getting?

[bizziboi]

I posted to an existing issue on the bitbucket page here:
https://bitbucket.org/rude/megasource/i ... uild-fails

It seems that when love2d builds it tries to build freetype while including the zlib.h from the zlib directory instead of its own private version. I tried working around it but without luck. Megasource itself builds fine for me, love fails building from VS or the command line.

The errors are (first few anyhow, behaviour changes if I have it include the private zlib, but still fails to build):
InitializeBuildStatus: Touching "freetype.dir\Release\freetype.tlog\unsuccessfulbuild". ClCompile: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\CL.exe /c /IC:\megasource\build\freetype\include /I"C:\megasource\libs\freetype-2.6.2\include" /I"C:\megasource\libs\freetype-2.6.2." /I"C:\megasource\libs\zlib-1.2.8." /IC:\megasource\build\zlib /nologo /W0 /WX- /MP /O2 /Ob2 /Oy- /D WIN32 /D _WINDOWS /D NDEBUG /D FT2_BUILD_LIBRARY /D "CMAKE_INTDIR=\"Release\"" /D _MBCS /Gm- /MD /GS /arch:IA32 /fp:precise /Zc:wchar_t /Zc:forScope /Fo"freetype.dir\Release\" /Fd"freetype.dir\Release\vc120.pdb" /Gd /TC /analyze- /errorReport:queue "C:\megasource\libs\freetype-2.6.2\src\gzip\ftgzip.c" ftgzip.c C:\megasource\libs\zlib-1.2.8.\zlib.h(86): error C2016: C requires that a struct or union has at least one member [C:\megasource\build\freetype\freetype.vcxproj] C:\megasource\libs\zlib-1.2.8.\zlib.h(86): error C2061: syntax error : identifier 'z_const'

This is why I wonder if it's just me, it could be that my default VC include paths are messed up.

[slime]

Some people have that error, but it hasn't happened to me or the nightly builds on Appveyor, so it makes tracking down the actual problem kind of hard.

A new version of FreeType was released a little while ago, I'll try updating megasource's copy of it this weekend to see if it helps, maybe.

[bizziboi]

Hmmm, that's odd.

Is there any way to get insight in what's installed on the buildmachine for the nightly build/AppVeyor? OS, versions, service packs, whatnot?
Does the buildmachine do clean builds, or just build changes?

It seems obvious that the makefiles are missing a dependency and rely on something being set a certain way in the build environment if it fails in a similar way on some machines but not others.

I guess I'll start by installing an older version of cmake, building from a different account, I don't have access to another machine (well, I do but it has a cmake that's too old and I can't upgrade it)

[bizziboi]

Okay, installing Cmake 3.0 instead of latest stable made it build for me (I guess CMake added an option that does not default to previous behaviour.....yeah, hmmmmm.....).

Note that the documentation states cmake 2.8.12 or up, but that won't generate VS2013 solutions.

[bizziboi]

Well, this sucks.

Just grabbed latest and the problem is back.
The cmake files now need at least CMake 3.1,(it used to work with 3.0) but cmake 3.1 will misgenerate the solution and the project will not build, at least not from Visual Studio 2013, the same bug with freetype is back.

[bizziboi]

Okay, found it.
Commit 991f387 broke it, as it mandates minimum CMake 3.1 - Windows won't build with projects generated with a CMake newer than 3.0.

(does the buildmachine actually do a full clean (ie regenerate) and rebuild? I'm really surprised this works for the buildmachine)

A couple of quick questions on topic.
I've installed a distro called SliTaz. A neat lightweight distro.
The thing is, love2d 0.10 requires gcc 4.7 whereas Slitaz have gcc of version 4.6.3.
Is it true that 4.7 is really needed due to it's features, or I can "fix" the sources to compile with 4.6.3?

Now, love2d 0.9 can be compiled with gcc 4.6.3, but it requires libdevil. Which seemingly builds

but love2d still doesn't see it (I did re-run ./configure):

How to tell love2d "Hey! *Here* is where the DevIl is!"?

It's a shame that deb/rpm-converted packages can't install liblove...

[bartbes]

A couple of quick questions on topic.

I'm not sure I'd consider hijacking a topic to be on-topic.

Is it true that 4.7 is really needed due to it's features, or I can "fix" the sources to compile with 4.6.3?

In the LÖVE codebase we picked a set of (old!) compilers to target, which includes gcc 4.7. To put this in perspective: gcc 4.7 was released in 2012. Even debian, known for its old packages in the stable version, ships gcc 4.7 in the previous stable version. Now, I'm not saying it will be impossible to compile with an older gcc version, but you'll probably have to modify a bunch of things yourself.

How to tell love2d "Hey! *Here* is where the DevIl is!"?

Conveniently, the configure script has a help option (--help) which shows you all the ways you can tell it how to find stuff. Since DevIL installed a pkg-config file (outside of its normal search path), it's probably easiest to override that, as follows:

Code: Select all

./configure PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

Alternatively, you can specify devil_CFLAGS and devil_LIBS yourself, their values would probably by "-I/usr/local/include" and "-L/usr/local/lib -lIL", respectively.

(does the buildmachine actually do a full clean (ie regenerate) and rebuild? I'm really surprised this works for the buildmachine)

Yes, it does. And it does build with VS2013, you can find the script here: https://bitbucket.org/rude/love/src/eaf ... pveyor.yml
