Compiler errors #3

Closed cpalmer9 closed 9 years ago

cpalmer9 commented 9 years ago

Hi there, We are getting the following errors when running 'make'.

Should the result of system(cmd) be assigned to something that then be checked?

ptm_conf.c: In function 'ptm_conf_topo_action': ptm_conf.c:138: error: ignoring return value of 'system', declared with attribute warn_unused_result ptm_conf.c:143: error: ignoring return value of 'system', declared with attribute warn_unused_result cc1: warnings being treated as errors ptm_event.c: In function 'main': ptm_event.c:562: error: ignoring return value of 'fscanf', declared with attribute warn_unused_result ptm_event.c:581: error: ignoring return value of 'daemon', declared with attribute warn_unused_result ptm_event.c:584: error: ignoring return value of 'ftruncate', declared with attribute warn_unused_result

Which environment are you compiling in ? I will try to repro it locally.

cpalmer9 commented 9 years ago

Oracle Linux Server release 6.3 gcc-4.4.6-4.el6.x86_64 glibc-headers-2.12-1.80.el6_3.6.x86_64

Chris is this still an issue?

cpalmer9 commented 9 years ago

We've worked around it. I'm going to try and rebuild against Oracle Linux Server release 6.5 at some point to see if things are cleaner.

I didn't see this issue when I rebuilt PTM on an OEL 6.5 Server.
