Building exiv2 0.27.xxx on MSYS2 #1102

gaaned92 · 2020-02-15T11:17:37Z

Context:
see https://discuss.pixls.us/t/art-v1-0-is-out/16103/155
"the official exiv2 version in Mingw seems broken, or at least miscompiled. it seems libexiv2.dll doesn’t properly raise exceptions on error. if I compile it myself, everything works"

The tag 0.27.2 builds ok on Mingw64 even if I get warnings.

As it is rather old, I tried to build 0.27.-maintenance branch commit hash 5360d82, hoping to benefit from last updates in metadata decoding.
Unfortunately I get errors.

Master branch cannot be built either due to other errors, but I understand that API change compared to 0.27 so it is not a concern now.

The text was updated successfully, but these errors were encountered:

clanmills · 2020-02-15T23:08:07Z

Thanks for reporting this. I have a couple of points of good news for you concerning 0.27.2 and 0.27-maintenance.

I've pulled down and successfully built a fresh clone of 0.27-maintenance on msys/2 with GCC 7.3.0 and cmake 3.10.2
Yesterday, a user reported getting the "official" 0.27.2 MinGW build to work with Qt Cannot link exiv2 prebuilt binaries in Qt project #1101

My suspicion is the toolchain for GCC 9.2.0.

I don't have any comment to make concerning 'master' on MinGW. It sounds as though you don't want to use it at this time, so let's not bother with that and focus on

getting 0.27.2 to build for you
using the pre-built 0.27.2 binaries.

gaaned92 · 2020-02-16T07:32:35Z

Thanks for answer.

the dll of 0.27.2 shipped with MINW64 seems broken
as I wrote i my first post, 0.27.2 builds ok and the dll links and works ok with ART
I tried to build 0.27-maintenance ( to benefit from last updates in decoding) and it fails.

So I think there was some commit between 0.27.2 and 0.27-maintenance that broke the build process

clanmills · 2020-02-16T10:16:05Z

I built a fresh clone of 0.27-maintenance with GCC 7.3.0 today. I'm more suspicious of GCC 9.2.0.

Yesterday, a user reported successfully linking the 0.27.2 MinGW build with Qt, so there can't be much wrong. However, it was built with GCC 7.3.0 and it's possible that it cannot link with applications built with GCC 9.2.0

Can you try using GCC 7.3.0?

gaaned92 · 2020-02-16T14:56:58Z

Ah! something broke in my msys2 installation after downgrading. Don't know if it is linked!

gaaned92 · 2020-02-17T14:40:37Z

Downgrading GCC breaks Cmake. So not very possible.

It doesn't seem a Windows problem but a exiv2 problem as some commits from 2.7.2 to 2.7- maintenance hinder the possibility to build with MSYS2/MINGW64/GCC9.2. Or perhaps it is a MINGW64 problem.
About GCC9.2.0, I can build Rawtherapee, ART, Darktable, Lensfun, exiv2 2.7.2, HDRMERGE, SIRIL, LuminanceHDR.
I am not sure this bug is related to windows, but more certainly to incompatibility with up to date MINGW64 chaintool, compiler, linker.. So to say, no specific Windows knowledge (API...) seems required to solve the issue.

clanmills · 2020-02-18T12:15:38Z

It built OK for me with CMake 3.10.2 and GCC 7.3.0.

The 0.27-maintenance branch is for development and doesn't promise to build every platform for every commit.

The matrix of branches/releases/tools is infinite. No release (such as 0.27.2 or even 0.27) can promise to build with every future tool-set.

gaaned92 · 2020-02-19T09:58:08Z

0.27.2 builds with gcc 9.2
The offending commit is 1fa5839. after that commit the branch cannot be built with 9.2.

It built OK for me with CMake 3.10.2 and GCC 7.3.0.
So all is good!

clanmills · 2020-02-19T13:05:48Z

Thanks @gaaned92. I'm very pleased to hear that this is fixed. I'm going to reopen this and ask @piponazo (who is Team Exiv2's CMake/Maestro) to comment on this.

clanmills · 2020-03-25T14:22:14Z

No response from Luis (piponazo). I'm going to close this.

@gaaned92 I'm working on Exiv2 v0.27.3 The schedule is to have a release candidate in early June and GM at the end of June.

gaaned92 · 2020-04-23T09:18:16Z

clanmills · 2020-04-23T09:32:41Z

Ah yes. GCC 9.3.0 doesn't build our code. I'm using GCC 7.4.0 which is provided in: http://repo.msys2.org/distrib/x86_64/msys2-x86_64-20190524.exe

We've also had trouble with GCC 8.2.0 which was thoroughly investigated #421 The user reported a bug to GCC and I've heard nothing about it. I don't believe it's in the Exiv2 code, so regretfully, I can't do anything else about this. I recommend you install and build with GCC 7.4.0 If you need GCC 9.3.0 for your own purposes, you can build Exiv2 with 7.4.0 and install it. When you compile your code with 9.3.0, it will link to Exiv2/7.4.0

D4N · 2020-04-23T09:38:46Z

This looks like the mingw bug that requires you to link with -lssp if you are using `FORTIFY_SOURCE=2` (which we are afaik adding). Could you try to either remove `-DFORTIFY_SOURCE=` from the C/CXXFLAGS or add -lssp to LDFLAGS?

clanmills · 2020-04-23T09:45:57Z

@D4N Great insight. The msys2 build sets (from the output of CMake/msys2)

-- General:
         -fstack-protector-strong
         -Wp,-D_GLIBCXX_ASSERTIONS
         -Wp,-D_FORTIFY_SOURCE=2
         -Wall
         -Wcast-align
         -Wpointer-arith
         -Wformat-security
         -Wmissing-format-attribute
         -Woverloaded-virtual
         -W

The code to set this is here:

527 MSYS rmills@rmillsmm-w10:~/gnu/github/exiv2/buildserver/build $ grep -i fortify ../cmake/*.cmake
../cmake/compilerFlags.cmake:            add_compile_options(-Wp,-D_FORTIFY_SOURCE=2) # Requires to compile with -O2
528 MSYS rmills@rmillsmm-w10:~/gnu/github/exiv2/buildserver/build $

@gaaned92 Can you try that, please. I can disable that in v0.27.3 RC, in much the same way that I've "tweaked" the compiler options for other platforms:

528 MSYS rmills@rmillsmm-w10:~/gnu/github/exiv2/buildserver/build $ grep -i sol ../cmake/*.cmake
../cmake/compilerFlags.cmake:        if (NOT MINGW AND NOT CMAKE_HOST_SOLARIS)
../cmake/packaging.cmake:elseif ( CMAKE_SYSTEM_NAME STREQUAL "NetBSD" OR CMAKE_SYSTEM_NAME STREQUAL "FreeBSD" OR CMAKE_HOST_SOLARIS)
../cmake/packaging.cmake:if ( CMAKE_SYSTEM_NAME STREQUAL "NetBSD" OR CMAKE_SYSTEM_NAME STREQUAL "FreeBSD" OR CMAKE_HOST_SOLARIS )
529 MSYS rmills@rmillsmm-w10:~/gnu/github/exiv2/buildserver/build $

gaaned92 · 2020-04-23T10:19:07Z

@clanmills
Thanks !
I suppressed

../cmake/compilerFlags.cmake: add_compile_options(-Wp,-D_FORTIFY_SOURCE=2) # Requires to compile with -O2

Build is ok. I will test ART with this version.

If you want I test also the other modification, please show me where and how to add -lssp to LDFLAGS.

I'll submit that to branch 0.27-maintenance today.

@gaaned92 FYI exiv2 v0.27.3 RC1 is on track for release on 2020-04-30

Fix submitted and merged in 0.27-maintenance #1175

clanmills · 2020-05-06T08:53:29Z

I've been working with @piponazo on C++11 support for 0.27.3 RC2 (scheduled on 2020-05-30) in the branch add_c++11_support_0.27. I've built Exiv2 with GCC 9.3 on both MinGW/msys2 and Cygwin/64. I'm very confident this trouble is resolved.
