Package: pkg-config Version: 0.29.2-1 Severity: important "pkg-config --cflags" incorrectly omits -I flags, potentially yielding errors, or even incorrect builds because a wrong .h file could be included. This happens when a CPATH or C_INCLUDE_PATH environment variable has the include dir.
Example: zira% pkg-config --cflags fplll -pthread -I/home/vinc17/opt/fplll/include zira% CPATH=/home/vinc17/opt/fplll/include pkg-config --cflags fplll -pthread zira% C_INCLUDE_PATH=/home/vinc17/opt/fplll/include pkg-config --cflags fplll -pthread At least with C_INCLUDE_PATH, this is incorrect because this environment variable is ignored by g++. Not sure about CPATH, but it would be safer to ignore it as well in case it would be unset or it would not be taken into account by some compiler (it is not specified by POSIX). -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-4-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=POSIX, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages pkg-config depends on: ii libc6 2.31-9 ii libdpkg-perl 1.20.7.1 ii libglib2.0-0 2.66.7-1 pkg-config recommends no packages.
