qsort_r previous declaration failure when building on musl libc

Open craftyguy opened this issue 1 year ago • 5 comments

qsort_r configuration at build time fails to do the right thing for me when building 2.6 with musl libc:

/home/clayton/src/aports/community/stellarsolver/src/stellarsolver-2.6/stellarsolver/astrometry/include/astrometry/os-features.h:123:17: error: conflicting types for 'qsort_r'; have 'void(void *, size_t,  size_t,  void *, int (*)(void *, const void *, const void *))' {aka 'void(void *, long unsigned int,  long unsigned int,  void *, int (*)(void *, const void *, const void *))'}

It never worked correctly on <2.6 either, in order to get 2.5 to build correctly I had a patch that basically just forced this config:

#define NEED_DECLARE_QSORT_R 0
#define NEED_QSORT_R 0
#define NEED_SWAP_QSORT_R 1

This trick no longer works on 2.6, and using the cmake logic in stellarsolver 2.6 doesn't work either.

I thought the QSortR declaration issues were improved upstream by the astrometry team. I had hoped that this contribution had improved that: https://github.com/rlancaste/stellarsolver/pull/139. Did this change cause the issue you are reporting?

Since Qt5 is being unmaintained from the 26th of May (this month!) I've been trying to get this to compile with Qt6, but I can sadly reproduce the same problem as @craftyguy (also on Alpine Linux).

I guess the original problem was fixed but qsort_r is very much still a problem.

Aside from a segfault in the test suite this seems to fix the qsort issue:

Essentially the order if const and non-const arguments in the callback function was wrong in multiple places.

Also the removal of code from os-features-test.c broke automated test completely since test compilation now always fails with undefined reference to `main': https://github.com/rlancaste/stellarsolver/pull/139/files#diff-ab098867e3d6840103789db63646fa629a1558eecee4fc3d9284dfbf4d93756a

Looking at #139 it seems to me that it broke more things than it fixes
