macos 14.2 Compile Gfortran-13.2 using gtk-4-fortran --Error linker mapping

[FR54T]

Hi,

I have some issue with generated compile with gtk-fortran in mac, here the information i attacht:
and sory im newbie in fortran too

Steps to reproduce to compile file bazzars.f90 the behavior is:

1. using bazzar.f90 on zsh and bash terminal
2. gfortran bazaar.f90 $(pkg-config --cflags --libs gtk-4-fortran)

Error Information:

ld: unknown option: -R/usr/local/lib
collect2: error: ld returned 1 exit status

Cause Error investigate :

file config error at: /usr/local/lib/pkgconfig gtk-4-fortran.pc

cause error: Xlinker path :Libs: -Xlinker -R${libdir} -l${libname} on gtk-4-fortran.pc

How to resolve it? Many Thanks

Your system:

• OS version: [MacosX 14.3 64 bits]
• Terminal using: Zsh and bash
• Gtk-Fortran version: Gtk-Fortan 4.5
• Architecture: Intel X86_64
• Compiler version: [GCC 13.2.0 gfortran 13.2.0]
• GTK branch: gtk4 macos via homebrew

Additional context
trying with all option with cmake config still error.

Welcome @FR54T

have you typed the following commands?

$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
$ export LIBRARY_PATH=/usr/local/lib/

See https://github.com/vmagnin/gtk-fortran/wiki/Installation#macos

Welcome @FR54T

have you typed the following commands?

$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
$ export LIBRARY_PATH=/usr/local/lib/

See https://github.com/vmagnin/gtk-fortran/wiki/Installation#macos

yes, this path already insert to path profile before iam installing gtk-fortran

[vmagnin]

A few question to try to understand the problem:

• Have you installed gtk-fortran with the command sudo make install ?
• What is the result of the command pkg-config --cflags --libs gtk-4-fortran ?
• Do you see the gtk-fortran library when typing ls /usr/local/lib ?

[FR54T]

Hii,

Have you installed gtk-fortran with the command sudo make install ? I has follow instruction from https://github.com/vmagnin/gtk-fortran/wiki/Installation#macos --for with sudo make install

What is the result of the command pkg-config --cflags --libs gtk-4-fortran ?

Do you see the gtk-fortran library when typing ls /usr/local/lib ? yes, heres for list gtk-fortran libs
ls /usr/local/lib
libgtk-4-fortran.4.5.0.dylib libgtk-4-fortran.a libgtk-4-fortran.dylib

heres for anaother comand $ gtk-4-fortran from terminal:
why information gtk-4-fortran version on my console.
$ gtk-4-fortran
(GTK 4.12.3 and GLib 2.78.1)
Compiled with GCC version 13.2.0 on ?, linked to GTK 4.12.4

Thanks

In Linux the end of the pkgconfig command is:

...
-Xlinker -R/usr/local/lib -lgtk-4-fortran -lgtk-4 -lpangocairo-1.0 -lpango-1.0 -lharfbuzz -lgdk_pixbuf-2.0 -lcairo-gobject -lcairo -lgraphene-1.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0

But in your output I can not see -R/usr/local/lib.

I will try to investigate when I have access to a macOS machine.

The <unknown> strings in the output of your gtk-4-fortran command is also odd. But it could be unrelated to the other problem (or not?). It comes from this line in src/gtk-fortran.f90:

    call c_f_string_copy_alloc(g_get_prgname(), name_string)

And if you run the ctest command in the gtk-fortran/build/ directory, do the examples run?

[FR54T]

Hi,

I Has Test , pls see the result.

But in your output I can not see -R/usr/local/lib.

I have made some tests on a macOS 12.7:
the pkg-config does return ... -Xlinker -R/usr/local/lib -lgtk-4-fortran ... but the -R does not seem to be recognized by the ld linker. But by manually replacing -R by -L it works.

Can you try to edit the gtk-fortran/src/gtk-fortran.pc.in file? The last line is:

Libs: -Xlinker -R${libdir} -l${libname}

• Just replace -R by -L
• Then rebuild (maybe not necessary) and reinstall gtk-fortran with sudo make install
• Retry gfortran bazaar.f90 $(pkg-config --cflags --libs gtk-4-fortran)

On my side, I will investigate further the exact definitions of those two -R and -L options.

[FR54T]

Hii, @vmagnin

Thank You. Its works now. gfortran compiling bring -- a.out now.

what kind diffrent for -R and -L explanation for base Linux and Macos on cmake process ouput ? any clue

[vmagnin]

Maybe we should use:

-Xlinker -rpath /usr/local/lib -L/usr/local/lib -lgtk-4-fortran

My understanding is that -rpath (or -Rdirectory) is for .so and -L for .a libraries, which are both in that directory /usr/local/lib

The GNU linker ld manual:
https://sourceware.org/binutils/docs/ld/

The line Libs: -Xlinker -R${libdir} -l${libname} is in gtk-fortran since May 2011. I must therefore investigate and discuss further with people familiar with linking problems before modifying it...

[vmagnin]

The macOS linker ld64 does not accept the GNU ld syntax -Xlinker -rpath=${libdir}, but would accept a space instead of =. In that case -Xlinker must be used twice to pass each part of the option to the linker:

-Xlinker -rpath -Xlinker ${libdir}

But curiously, I had a problem with pkgconfig in Ubuntu with that syntax, the first -Xlinker being not returned (I have instead obtained: -rpath -Xlinker /usr/local/lib).

Happily, there is an alternative syntax with the -Wl option that is correctly treated in all systems:

-Wl,-rpath,${libdir}

Here, there is only one option -Wl with the different parts of the option to pass to the linker separated by commas.

Note that the -rpath option is writting the library path directly inside the executable, as can be verified by this command:

$ readelf --dynamic a.out

Finally, I have also decided to add the missing -L option that "add path searchdir to the list of paths that ld will search for archive [static] libraries and ld control scripts". The last line of the pkgconfig file is now therefore:

Libs: -L${libdir} -Wl,-rpath,${libdir} -l${libname}

I have pushed it in my dev branch https://github.com/vmagnin/gtk-fortran/tree/gtk4-vmagnin where I will prepare the next release (probably in May), and tested linking in macOS, Ubuntu, Fedora, FreeBSD and MSYS2/Windows10.

[vmagnin]

Fixed in gtk-fortran 4.6.0.
