Bug 18188 – rdmd ignores dependency in 'static this()'

There are cases when rdmd ignores the local imports defined in 'static this()'. Moving 'import baz' out of static this will give the expected result. See the example bellow. // foo.d void main() { import bar; } // bar.d static this() { import baz : baz; baz; } // baz.d int baz() { return 0; } $ rdmd --build-only --chatty foo.d mkdirRecurse /tmp/.rdmd-500 mkdirRecurse /tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F lock /tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F/rdmd.lock mkdirRecurse /tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F/objs stat /tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F/rdmd.deps spawn ["/usr/bin/dmd", "-v", "-o-", "foo.d", "-I."] read /tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F/rdmd.deps which /usr/bin/dmd stat /etc/dmd.conf stat /tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F/.built stat ./foo stat foo.d stat foo.d stat /etc/dmd.conf stat bar.d stat /usr/bin/dmd stat ./foo spawn ["/usr/bin/dmd", "-of./foo.tmp", "-od/tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F/objs", "-I.", "foo.d", "bar.d"] /tmp/.rdmd-500/rdmd-foo.d-882FBF761B809294731EC3E5E391C36F/objs/foo.o: In function `_D3bar12_staticCtor1FZv': bar.d:(.text._D3bar12_staticCtor1FZv[_D3bar12_staticCtor1FZv]+0x5): undefined reference to `_D3bazQeFZi' collect2: error: ld returned 1 exit status Error: linker exited with status 1

The problem is caused by `dmd -v` output, that is parsed and used by rdmd. $ dmd -v -o- foo.d predefs DigitalMars Posix linux ELFv1 LittleEndian D_Version2 all D_SIMD D_InlineAsm_X86_64 X86_64 CRuntime_Glibc D_LP64 D_PIC assert D_HardFloat binary dmd version v2.078.0 config /etc/dmd.conf parse foo importall foo import object (/usr/include/dmd/druntime/import/object.d) semantic foo entry main foo.d semantic2 foo semantic3 foo import bar (bar.d) Calling dmd with -deps option fixes the problem: $ dmd -v -o- foo.d -deps=/dev/null predefs DigitalMars Posix linux ELFv1 LittleEndian D_Version2 all D_SIMD D_InlineAsm_X86_64 X86_64 CRuntime_Glibc D_LP64 D_PIC assert D_HardFloat binary dmd version v2.078.0 config /etc/dmd.conf parse foo importall foo import object (/usr/include/dmd/druntime/import/object.d) semantic foo entry main foo.d semantic2 foo semantic3 foo import bar (bar.d) import baz (baz.d) Consequently rdmd command also functions when -deps option is added: $ rdmd --build-only --chatty -deps=/dev/null foo.d mkdirRecurse /tmp/.rdmd-500 mkdirRecurse /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756 lock /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/rdmd.lock mkdirRecurse /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/objs stat /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/rdmd.deps spawn ["/usr/bin/dmd", "-deps=/dev/null", "-v", "-o-", "foo.d", "-I."] read /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/rdmd.deps which /usr/bin/dmd stat /etc/dmd.conf stat /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/.built stat ./foo stat foo.d stat foo.d stat /etc/dmd.conf stat baz.d stat bar.d stat /usr/bin/dmd stat ./foo spawn ["/usr/bin/dmd", "-deps=/dev/null", "-of./foo.tmp", "-od/tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/objs", "-I.", "foo.d", "baz.d", "bar.d"] stat /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/objs rmdirRecurse /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/objs mv ./foo.tmp ./foo touch /tmp/.rdmd-500/rdmd-foo.d-2D7BE73D8EB3145BDB8A563EF51C3756/.built

BTW are you aware of https://github.com/dlang/dmd/pull/7099 and https://github.com/dlang/tools/pull/271 ? It could as a side-effect fix your bug.

the 2 PR didn't fix the issue. The problem is still present in dmd 2.086.

rdmd will be deprecated. Instead use: > dmd -i -run foo.d
