[opensuse-packaging] Failure from no-return-in-nonvoid-function test
I am trying to build the latest version of python-numpy. However, the build is failing with the following problem: [ 370s] ... running 01-check-debuginfo [ 370s] ... testing for empty debuginfo packages [ 370s] ... running 02-check-gcc-output [ 370s] ... testing for serious compiler warnings [ 370s] (using /usr/lib/build/checks-data/check_gcc_output) [ 370s] (using //.build.log) [ 371s] [ 371s] I: Program returns random data in a function [ 371s] E: python3-numpy no-return-in-nonvoid-function _configtest.c:8 [ 371s] [ 371s] I: Program returns random data in a function [ 371s] E: python3-numpy no-return-in-nonvoid-function _configtest.c:8 The problem is that there is no "_configtest.c" file in the sources or binaries. It seems to be a file that is built temporarily to test build configuration, then deleted. There are a bunch of warnings during the build, but I cannot determine which (if any) is responsible for the failure, so I can't figure out where to begin looking to fix it. You can see an example build log here: https://build.opensuse.org/package/live_build_log/home:TheBlackCat:branches:... Does anyone have any idea what is causing this failure, or at the very least which of the warnings it is talking about? -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org

yes, _configtest.c is coming from distutils. The offending function is generated from numpy/core/setup.py lines 183-186 and looks like this: 1: int __declspec(thread) a; 2: #ifdef _MSC_VER 3: #pragma function(__declspec(thread)) 4: #endif 5: int main (void) { 6: __declspec(thread); 7: return 0; 8:} the warning in question is "control reaches end of non-void function [-Wreturn-type]", and in this case the build check is totally spurious -- the offending program doesn't even compile. not sure what to do about this. disable "-Wall" for config checks? explicitly remove "__declspec(thread)" from OPTIONAL_FUNCTION_ATTRIBUTES (this is probably the simplest fix)? disable the build check? hope this helps m.

That seems to have worked. Thanks! On Tue, Sep 9, 2014 at 4:29 PM, Jan Matějek <jmatejek@suse.cz> wrote:

yes, _configtest.c is coming from distutils. The offending function is generated from numpy/core/setup.py lines 183-186 and looks like this:
1: int __declspec(thread) a; 2: #ifdef _MSC_VER 3: #pragma function(__declspec(thread)) 4: #endif 5: int main (void) { 6: __declspec(thread); 7: return 0; 8:}
the warning in question is "control reaches end of non-void function [-Wreturn-type]", and in this case the build check is totally spurious -- the offending program doesn't even compile.
not sure what to do about this. disable "-Wall" for config checks? explicitly remove "__declspec(thread)" from OPTIONAL_FUNCTION_ATTRIBUTES (this is probably the simplest fix)? disable the build check?
