So the visibility switches seem to come out of the blue, presumingly during the configure stage… (which I cannot perform because boost176 is being built – until tomorrow?)

[ryandesign (Ryan Carsten Schmidt)]

Replying to ballapete:

So the visibility switches seem to come out of the blue, presumingly during the configure stage…

Probably from here and other instances in this file:

​https://github.com/libjxl/libjxl/blob/e1489592a770b989303b0edc5cc1dc447bbe0515/lib/jxl.cmake#L65-L66

libjxl-0.10.2/lib/jpegli.cmake starts an if here:

 53 if(JPEG_FOUND AND BUILD_TESTING)
 54 # TODO(eustas): merge into jxl_tests.cmake?

that might end with (there are more if then endif):

152 # This hides the default visibility symbols from static libraries bundled into
153 # the shared library. In particular this prevents exposing symbols from hwy
154 # in the shared library.
155 if(LINKER_SUPPORT_EXCLUDE_LIBS)
156   set_property(TARGET jpeg APPEND_STRING PROPERTY
157     LINK_FLAGS " ${LINKER_EXCLUDE_LIBS_FLAG}")
158 endif()
159 endif()

This might be too specific for JPEG only…

libjxl-0.10.2/lib/jxl.cmake has:

240 # Add a jxl.version file as a version script to tag symbols with the
241 # appropriate version number. This script is also used to limit what's exposed
242 # in the shared library from the static dependencies bundled here.

It's all a bit indirect and not comprehensible for me, no old stuff, too modern. I'll execute the configure stage and check again for the existence of the C++ switches!

[ballapete (Peter "Pete" Dyballa)]

After this step the following files contain the visibility switches:

./build/CMakeFiles/CMakeConfigureLog.yaml
./build/compile_commands.json
./build/lib/CMakeFiles/jxl_cms.dir/flags.make
./build/lib/CMakeFiles/jxl_dec-obj.dir/flags.make
./build/lib/CMakeFiles/jxl_enc-obj.dir/flags.make
./build/lib/CMakeFiles/jxl_export.dir/flags.make
./build/lib/CMakeFiles/jxl_threads.dir/flags.make

The last five make files are presumingly the responsible ones…

[ballapete (Peter "Pete" Dyballa)]

At [ 43%], when Linking CXX shared library libxml_cms.dylib, the ld warnings on different visibility settings appear again. Although before none of the visibility switches was used for compilation…

[ballapete (Peter "Pete" Dyballa)]

Same failure as before…

[ballapete (Peter "Pete" Dyballa)]

Main.log from PPC Leopard, Mac OS X 10.5.8, faulty build again without visibility

[kencu (Ken)]

the final error is

info:build ld: illegal text-relocation to lC14 in ../lib/libjxl_extras-internal.a(metrics.cc.o) from jxl::N_SCALAR::ComputeDistanceP(jxl::Plane<float> const&, jxl::ButteraugliParams const&, double) in ../lib/libjxl_extras-internal.a(metrics.cc.o) for architecture ppc
5060	:info:build collect2: error: ld returned 1 exit status

so you could try adding this:

configure.ldflags-append -Wl,-read_only_relocs,suppress

[ballapete (Peter "Pete" Dyballa)]

Leaving the visibility switches as introduced by the build process, it built with the additional LDFLAGS.

To check whether dvisvgm @3.3 can exist without MuPDF I am performing a make check outside of MacPorts (just let it fetch and extract). I see here similar ld warnings when building with GCC7. (Plus a lot more.) Could the cause be that some files are compiled with gcc and others with g++? With dvisvgm a libmd5.a is used which is an item built from objects made by gcc or by g++…
