Hello,
Libguile in 3.0.0 lacks all the C exports for variables created with
‘SCM_GLOBAL_SYMBOL’ in ‘expand.c’:
--8<---------------cut here---------------start------------->8---
$ objdump -T
/gnu/store/b9xkl8vbxbyblzkwp7xzwwmharswkbgy-guile-2.2.6-1/lib/libguile-2.2.so
|grep scm_sym_lambda
000000000012c298 g DO .bss 0000000000000008 GUILE_2.0 scm_sym_lambda
$ objdump -T
/gnu/store/7z0zzqbchcjmc1krwhy0jd5hsny5y77w-guile-next-3.0.0/lib/libguile-3.0.so
|grep scm_sym_lambda
--8<---------------cut here---------------end--------------->8---
That’s because they accidentally ended up having the “hidden”
visibility, which is fixed by the patch below.
This will obviously augment the ABI. Should we push?
Thanks,
Ludo’.
