Main.log from PPC Tiger, Mac OS X 10.4.11

[ballapete (Peter "Pete" Dyballa)]

Actually /opt/local/bin/gcc-apple-4.2 does not understand any of the -Wno-<whatever> options, /opt/local/bin/gcc-apple-4.2 -v --help shows:

-Wno-comma
-Wno-date-time
-Wno-deprecated-declarations
-Wno-extra-semi-stmt
-Wno-float-equal
-Wno-format-nonliteral
-Wno-implicit-fallthrough
-Wno-missing-noreturn
-Wno-newline-eof
-Wno-nonportable-include-path
-Wno-nonportable-system-include-path
-Wno-pedantic
-Wno-reserved-id-macro
-Wno-reserved-identifier
-Wno-shadow
-Wno-sign-conversion
-Wno-switch-enum
-Wno-unknown-pragmas
-Wno-unknown-warning-option
-Wno-unused-macros
-Wno-unused-result

Clearly they must be removed from luametatex-2.10.08/CMakeLists.txt – or GCC7 used.

[ballapete (Peter "Pete" Dyballa)]

Proposed patch to remove unsuitable -Wno-<whatever> options from invocations of /opt/local/bin/gcc-apple-4.2 – to be tested soon

[ryandesign (Ryan Carsten Schmidt)]

Its CMakeLists.txt says:

set(CMAKE_C_STANDARD 11)

We could indicate that in the Portfile with:

compiler.c_standard 2011

That would cause MacPorts to select a newer compiler that hopefully understands those warning flags so no patch would be needed.

However, if I understand CMake correctly, that line in CMakeLists.txt is only indicating a preference for C11 if it is available, not that it is required. Does your patch removing those warning flags allow the port to build with GCC 4.2.1? If so, then C11 is clearly not required and your patch would be the way to go. In that case, please report the bug to the developers of luametatex. They should be testing the compiler for support of each warning flag before adding them.

[ballapete (Peter "Pete" Dyballa)]

The original patch has a flaw: the path component luametatex-2.10.08/ needs to be removed. With this change it applies – but a new failure rises:

luametatex-2.10.08/source/tex/textypes.h has:

   94	typedef posit32_t tex_posit;

I'll check whether line #93 can be deleted.

Without that re-definition the build continues and ends here with this well-known error (#67248):
