qcc doesn't understand -std=c99, causes issues with autotools (./configure)

[ Edited ]

The documented solution is to use -Wl to pass the param to the compiler, but this doesn't help much when trying to compile a library that uses autotools.


Adding -Wc,-std=c99 to CFLAGS causes configure's c99 tests to pass, which causes the Makefile to pass -std=c99 to qcc, which chokes.


Is there a clean way to fix this? I wish to avoid having to manually modify the configure file or the Makefile every time I want to build an open-source library.


Any chance the next version of qcc could understand -std?


Are there any reasons why it shouldn't? Is qcc open-source and does it accept patches?

Re: qcc doesn't understand -std=c99, causes issues with autotools (./configure)

A little late, but I was looking for the answer to this too.  I found it here:




Just add:


QMAKE_CFLAGS += -Wc,-std=c99

to your .pro file.


Probably too late to help you, but others may see this.
