From c8c8aeef0fcc6aba31b8d4775cfaec368f102604 Mon Sep 17 00:00:00 2001 From: Xavier Claessens Date: Wed, 23 Mar 2022 18:56:40 -0400 Subject: build.py: Simplify validate_sources() There is no need to go through all sources again, we already did that to populate self.compilers. When cs or java compilers are in the list, then there must be only one compiler. The code was also not considering generate sources any way. --- mesonbuild/build.py | 18 +++--------------- 1 file changed, 3 insertions(+), 15 deletions(-) (limited to 'mesonbuild/build.py') diff --git a/mesonbuild/build.py b/mesonbuild/build.py index 5c997e8..00a737a 100644 --- a/mesonbuild/build.py +++ b/mesonbuild/build.py @@ -971,21 +971,9 @@ class BuildTarget(Target): return missing_languages def validate_sources(self): - if not self.sources: - return - for lang in ('cs', 'java'): - if lang in self.compilers: - check_sources = list(self.sources) - compiler = self.compilers[lang] - if not self.can_compile_remove_sources(compiler, check_sources): - raise InvalidArguments(f'No {lang} sources found in target {self.name!r}') - if check_sources: - m = '{0} targets can only contain {0} files:\n'.format(lang.capitalize()) - m += '\n'.join([repr(c) for c in check_sources]) - raise InvalidArguments(m) - # CSharp and Java targets can't contain any other file types - assert len(self.compilers) == 1 - return + if len(self.compilers) > 1 and any(lang in self.compilers for lang in {'cs', 'java'}): + langs = ', '.join(self.compilers.keys()) + raise InvalidArguments(f'Cannot mix those languages into a target: {langs}') def process_link_depends(self, sources, environment): """Process the link_depends keyword argument. -- cgit v1.1
