GCC 13.2 Missing Headers

[hjmjohnson]

Description

Test compiling ITK 5.2.0 on the upcomming Ubuntu 24.04 release with gcc 13.2 compiler resulted in build errors due to fixes in include file pollution common in previous compilers.

This issue is intended to document a work around to a problem that may be common to many developers attempting to use newer compilers.

The

#include <limits>
#include <cstdint>

header files are not explicitly listed (previous compilers had them implicitly included).

# build hack to get around missing include files

cat > /tmp/extra_includes << EOF
#include <limits>
#include <cstdint>
EOF

ccmake -DCMAKE_CXX_FLAGS="-include /tmp/extra_includes" .

Try to compile ITK 5.2.0 on Ubuntu 24.04 (or gcc 13.2) compiler.

Expected behavior

Should build

Actual behavior

Fails build

Versions

At least 5.2.0

Environment

Ubuntu 24.04 environment.

@hjmjohnson this has been fixed in recent ITK, correct?

[hjmjohnson]

Yes. I'm getting a ton of warnings, but the compilation succeeded.
