Build fais with clang: version script assignment of 'global' to symbol 'ags_vst3_conversion_get_type' failed: symbol not defined

The core reason is that you have these symbol names in .sym files but they don't appear in any built binaries. The GCC toolchain appears to be forgiving with this problem, but clang is more rigorous.

Version: 6.12.5 clang-18.1.5 FreeBSD 14.0

Hi @yurivict

Check this commit:

https://github.com/gsequencer/gsequencer/commit/cedf2b40d13e1f8eab191f95c9b9ddde0ec021eb

You should be able to generate symbols like this:

make gen-symbols-all
make fix-symbols-all-bsd

I am just building another tarball.

Hi Joel,

I am curious, why are the symbols different on BSD? Does something fail to build or is something disabled that isn't disabled on Liux?

Thanks, Yuri

I am bit confused about sed and its use in Makefiles. Do you know a good resource about using sed with automake?

[yurivict]

sed in automake? No, I avoid automake as much as I can.

I get this failure:

[yurivict]

These commands don't solve the problem:

make gen-symbols-all
make fix-symbols-all-bsd

[joelkraehemann]

Is perl an option?

find ags/util -name ".h" -exec perl -ne 'while(/(?<=\s)(ags[a-z0-9]+)(?=[\s]()/g){print "$&\n";}' '{}' \;

[yurivict]

perl is possible.

[joelkraehemann]

FYI, I have just added the perl script to generate symbols:

https://github.com/gsequencer/gsequencer/blob/6.12.x/gen-symbols-all.pl

Note, if you modify symbols file run configure again because of these m4 macros:

https://github.com/gsequencer/gsequencer/blob/6.12.x/m4/ags-symbols.m4

[joelkraehemann]

You can do now following to generate symbols files:

./configure
make gen-symbols-all-bsd
make fix-symbols-all-bsd
./configure
make
make install

Fix included in 6.12.7
