Bug 931829 – dev-libs/apr-util-1.6.3: cross-compilation fails with /usr/aarch64-unknown-linux-gnu/bin/apr-1-config//usr/aarch64-unknown-linux-gnu/usr/share/apr/build: Not a directory

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description raffaele 2024-05-12 17:28:45 UTC]

Cross compilation of dev-libs/apr-util-1.6.3 fails with the following error in the build log:
./configure: line 13070: cd: /usr/aarch64-unknown-linux-gnu/bin/apr-1-config//usr/aarch64-unknown-linux-gnu/usr/share/apr/build: Not a directory

HOST is ~amd64, TARGET is ~arm64 (raspberry Pi4b).
The cross-toolchain was built with:

# crossdev --target aarch64-unknown-linux-gnu

Reproducible: Always

Steps to Reproduce:
1.as root, issue:
# emerge-aarch64-unknown-linux-gnu --buildpkg --ask --verbose --oneshot dev-libs/apr-util

[ebuild  N     ] dev-libs/apr-util-1.6.3:1::gentoo to /usr/aarch64-unknown-linux-gnu/ USE="gdbm -berkdb -doc -ldap -mysql -nss -odbc -openssl -postgres -sqlite -static-libs" 0 KiB

2. press <enter>

Actual Results:  
Build fails with the error in Description. As suggested the directory searched by ./configure does not exist. May it be instead "/usr/aarch64-unknown-linux-gnu/usr/share/apr/build/"?

Expected Results:  
Package built

[Comment 3 James Le Cuirot 2024-05-12 21:55:45 UTC]

Reproduced.

[Comment 4 James Le Cuirot 2024-05-12 22:02:11 UTC]

Changing --with-apr="${ESYSROOT}"/usr to --with-apr="${EPREFIX}"/usr fixed it for me until I removed apr-util from host. I was right to be suspicious! I'll take a closer look at exactly what it's doing.

[Comment 5 James Le Cuirot 2024-05-13 22:44:42 UTC]

Hmmm. This is caused by an old fix in bug #385775, which modifies apr-1-config to prefix some paths with SYSROOT. The problem is that the script already normalises its paths based on where it is executed from, but I'm guessing that wasn't the case back then. I'll try undoing at least some of that patch soon. Setting SYSROOT= while executing econf works, but that will probably break pkg-config, which is used for NSS.

    dev-libs/apr: Fix cross-compiling as using SYSROOT no longer works
    
    The old patch added SYSROOT to some paths shown by apr-config, but the script
    now also automatically adjusts the paths when it has been cross-compiled,
    leading to the paths being doubled. This removes the SYSROOT hack and forces
    it to consider that it might be cross-compiled.
