Building on older MacOS: build succeeds now, but app fails at launch with malloc errors

[barracuda156]

I am trying to fix rawstudio for Macports, where it is outdated and broken across the board for ages.

At some point of the build (rawstudio 2.0, 10.6.8 Rosetta, gcc12), there are multiple errors of this sort:

../../librawstudio/rawstudio.h:26:1: note: 'extern "C"' linkage started here
   26 | extern "C" {
      | ^~~~~~~~~~
/opt/local/include/gcc12/c++/type_traits:539:3: error: template with C linkage
  539 |   template<typename _Tp>
      |   ^~~~~~~~
In file included from /opt/local/inclu/opt/local/include/gcc12/c++/type_traits:590:3: error: template with C linkage
  590 |   template<typename _Tp>
      |   ^~~~~~~~
/opt/local/include/gcc12/c++/type_traits:464:3: error: template with C linkage
  464 |   template<typename _Tp>

I tried then moving <sys/types.h> out of conditional block (like it is done in some Apple headers):

#include <sys/types.h>

#ifdef  __cplusplus
extern "C" {
#endif

That changed nothing, I get same error. This still might be header positioning related, like: msgpack/msgpack-c#551
Any suggestions what is going wrong?

can be about glibc fix [1] you may try revert these two commits i.e. move [2] to before #include <sys/types.h>

@sergiomb2 Thank you. Since v. 2.0 had other bugs too, I moved to the latest-commit version, and it does not exhibit this problem.

Unfortunately, while it builds fine (with deprecated symbols warnings, but no errors), it fails to work for me:

This may not be a problem of rawstudio though. Older MacOS get these malloc errors time to time, and there is no neat fix for that: iains/darwin-toolchains-start-here#20

Rebuilt with gcc10-bootstrap, same thing:

And gcc-4.2 cannot build Rawspeed module :(

@catap Have you got any ideas how to go about those?

We have fixed this issue in Macports. Closing.
