This package often requires special care to build. If building this with makepkg fails it will be necessary to construct the package in a clean chroot. Using an AUR helper is not recommended; however, aurutils does provide the option to build in the clean chroot.

The process of building this package in a clean chroot is rendered exceptionally simple with the help of scripts in the devtools package and can be completed via the following steps. These summarize the information provided by the Arch Linux DeveloperWiki and assume familiarity with git or the process of downloading a snapshot from the AUR and extracting the archive. Please refer to this article for more information about the devtools scripts and building in the clean chroot: [https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot]

Prerequisites: This process uses scripts in devtools to simplify the procedure: please install this package before beginning. The lib32-libmng package is required and must be built or downloaded from the Arch Linux Archive [https://wiki.archlinux.org/index.php/Arch_Linux_Archive]. QT 4 depends on this package and it is no longer found in the binary repositories.

1. Clone the lib32-qt4 repository or extract the snapshot archive into a clean working directory.

2. Enter the directory containing the package source. (PKGBUILD and patches.)

3. Execute the following command, supplying the location of lib32-libmng: multilib-build -- -I /<somewhere>/lib32-libmng-2.0.3-1-x86_64.pkg.tar.xz

4. Execute pacman with the -U flag to install the resulting package: just as one would with any other local package. Note: lib32-libmng would need to be installed in a similar fashion if it isn't already present on your system.

The QT 4 build system is prone to some odd behaviour: especially if the qtwebkit package is installed. [https://bbs.archlinux.org/viewtopic.php?id=132416] [https://bugreports.qt.io/browse/QTBUG-20236]

If your build fails with the following [error: expected class-name before ‘{’ token] when compiling please build in a clean chroot.

If your build fails with error messages about skipping incompatible files and being unable to find a specific file in a compatible format, especially while linking, you will need to build in a clean container to avoid issues.

Building this package in a clean chroot or other form of container will prevent unexpected issues.

All build errors will be ignored unless the build was performed inside a clean, properly configured container. For more information about building in a clean chroot see this article: [https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot]

Big thanks to int [at] arcor [dot] de for doing the legwork to track down the relevant issue reports and sending them my way.

8XA: I do not encounter any issues when using the official download URL. If you're unable to successfully download the tarball from the URL in the source array I'd suggest http://master.qt.io/official_releases/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz as the best alternative.

The source has an error, I put this link instead: http://qt.mirror.constant.com/official_releases/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz Then, everything went OK.

ArnaudNux: I can not reproduce that error in a clean chroot. Please read the pinned comments and retry your build in a clean chroot.

I've merged the changes made in [Extra] to mend issues caused by ICU 60.1 and ensured lib32-icu is properly invited to the party if ICU is going to jump in and break the build.

I managed to get it to build by applying this[1] change from the qt4 [extra] package. It was related to the icu-60.1 version bump. I've pushed that change and an addition of lib32-icu (optional) dependancy to my github[2].

@rafaelff Did you read the two pinned comments from WoefulDerelict at the top? I have a bash script that did all the dirty work. It was working at some point, not sure if it still does, but for sure it's worth a try.

See here: https://gist.github.com/basilschneider/2422cebb355427d6f4063dfde52fb371

Note also the comments at the bottom. They might further help you if the build is still not working.

Build failed. Here is the build() output: https://ptpb.pw/Pf5p - any ideia?
