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: []

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 []. 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. [] []

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: []

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

The archlinuxgr repository contains a binary copy of this package courtesy of ranger.

darkbasic: While you are the first user to post a comment with that output it does not seem to be a new issue. If one parses the output correctly it appears that you attempted to build package release 10 against lib32-openssl 1:1.1.0.e which was known not to work. QT4 is not compatible with OpenSSL 1.1.0 and the issue was noted here when OpenSSL 1.1.0 hit testing. Release 11 should work so long as all the prerequisites have been met as it builds against a new lib32-openssl-1.0 package which should provide all the expected symbols.

Is this a new error? I already removed qtwebkit since a long time.

DellArch: After building one installs a local package with: pacman -U <path to pkg>

If one has just completed step 3 installing the result would be as simple as: pacman -U lib32-qt4 4.8.7-10-x86_64.pkg.tar.xz

DellArch commented on 2017-04-24 13:25

I followed the steps without any errors back, but running
$yaourt -Syua
I still have the package not upgraded

DellArch: You will need a copy of the lib32-libmng package present to include in the chroot and the devtools package must be installed if you want to use the multilib-build script as shown. Currently the package in the ALA is perfectly sound and there is not reason not to use it unless you really like building things locally. In step 3 "/<somewhere>/lib32-libmng-2.0.3-1-x86_64.pkg.tar.xz" is meant to be expanded by the user to wherever they stored the package file so the script can install it in the chroot as it isn't part of the repos. This is going to install a base copy of Arch Linux on your system with all the packages needed to build lib32-qt4 including lib32-libmng so be sure you have lots of free disk space or it is going to get messy fast.

Sorry guys, just to be sure, I find this error:

So, I have to make a back up of lib32-libmng (it is no ok the package on ALA?) and then follow the 3 steps of the pinned comment?
1 - download from ALA the .pkg.tar.xz
2 - run: cd "folder with package downloaded"
3 - run: multilib-build -- -I /<somewhere>/lib32-libmng-2.0.3-1-x86_64.pkg.tar.xz

Please, is possible to someone create a tutorial to use this "chroot" process? (or paste a link to some tutorial)

The comments doesn't give me the necessary details for some steps.

Thank you so much.

WARNING: This is not compatible with lib32-openssl 1:1.1.0.e-1 from [Multilib-Testing]. This should be binary compatible with 32-bit copies of openssl 1.0; however there is not yet a lib32-openssl-1.0 in [Multilib-Testing]. I've sent a message to the maintainer requesting a 32-bit openssl 1.0 package for compatibility with legacy binaries.

Mirror the added lines in [Extra]'s qt4 and testing the PKGBUILD against a personal staging package of lib32-openssl-1.0 produces some unexpected errors during linking. I have some leads and a possible solution but it is unlikely the update to openssl 1.1 with openssl 1.0 alongside it will be painless. Expect breakage.
