Re: [Quickfix-users] C++ O3 compilation

[Louis B. <lb...@or...>]

Hi Mike,

I am building from v1.15.1.

I was finally able to build it with -O3 and gcc 5.4.0 but had to comment out unit test FixturesWithThrowingDtorsAreFailures.

Thanks,

Louis,

Are you building from the latest github master, or from quickfix release v1.15.1 (or other)?

Using the latest from master, I'm able to successfully build and run the tests with -O3 using gcc v8.3.

Hi all,

I am trying to compile using the "-O3" flag instead of "-g -O2" but the unit tests fail:
# export CXXFLAGS="-O3"
# ./bootstrap
...
# ./configure
...
# make
...
Linking TestUnitTest++...
Running unit tests...
terminate called after throwing an instance of 'char const*'
Makefile:79: recipe for target 'TestUnitTest++' failed
make[2]: *** [TestUnitTest++] Aborted (core dumped)
...

The core does not display any usable information (I guess this is due to the -O3 flag).

On the other hand I can make in the quickfix/src directory and everything builds fine.

So, is O3 optimization "officialy" unsupported? Could I still used the library built using quickfix/src/make?

Thanks,


Louis Benoit
