Package: gdc-10 Version: 10.1.0-1 Severity: normal It is common to provide unittests for module in the module, but without main, so the module can be used as a library.
For this reasons, to test just one module one need to provide a dummy main function when linking. -fmain does this autoamtically in gdc. This feature is also available in dmd (-main) and in ldc2 (--main, not mentioned in the manpage, but shows in ldc2 --help). So the option in gdc is there, it is just not mentioned in gdc --help or in manpage, making it hard to find. -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.2.0-3-amd64 (SMP w/32 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages gdc-10 depends on: ii g++-10 10.1.0-1 ii gcc-10-base 10.1.0-1 ii libc6 2.30-8 ii libgmp10 2:6.2.0+dfsg-4 ii libgphobos-10-dev 10.1.0-1 ii libisl22 0.22.1-1 ii libmpc3 1.1.0-1 ii libmpfr6 4.0.2-1 ii libzstd1 1.4.4+dfsg-3 ii zlib1g 1:1.2.11.dfsg-2 gdc-10 recommends no packages. gdc-10 suggests no packages. -- no debconf information
