Re: Building TeXmacs for macos

Yes, I understand his problem is at build time.  I just wanted to point 
out that on another, perhaps somewhat similar,  OS there is no such problem.

I also forgot to add that

1) The compiler used is clang 10 (standard on FreeBSD)
2) TeXmacs 1.99.{13,14} not only builds, but also works fine, with the 
exception of plugins (pipes).
3) The situation with 1.99.15 is the same: TeXmacs builds, works, but 
not with plugins.

However independently of what is your running OS I was meaning that the headers of Big Sur should have changed, because there is no such problems with SDKs from previous systems (e.g. Catilina).

As I said, the error messages you get seems to come from changes in the headers which cause symbol clashes in TeXmacs. We had this kind of issues before due to the fact that various libraries might have incompatible #define

It is possible to build with qt 5, but for that to succeed, I had to change quite a few paths in makefile.

I think the instructions on the website regarding compiling TeXmacs from the sources should be edited to advice compiling with Qt4 and not Qt5. (No version is suggested there, which led me to believe the current version of Qt was the expected one, or at least as good as the previous one…)
