Hi/2.

I'm trying to build VLC with gcc 9.2.0. However, compilation fails due to out of memory.

make[4]: Entering directory 'F:/lang/work/vlc/vlc.git/modules'
  CXX      gui/qt/dialogs/libqt_plugin_la-dialogs_provider.lo

cc1plus.exe: out of memory allocating 65536 bytes after a total of 284622848 bytes
make[4]: *** [Makefile:31764: gui/qt/dialogs/libqt_plugin_la-dialogs_provider.lo] Error 1

Any ideas ?

Hi/2 to you too. :-)

This usually means that the assembler has defaulted to building a 16-bit
object module. Paul ran into this with his qt5/qt6 builds. I don't
recall exactly what assembler options needed to change.

I had those errors when building Qt5, restarting the computer fixed it
for a while. Had to restart a few times to succeed.
Also VIRTUALADDRESSLIMIT=3072 and nothing much else running.
We're at the limits of our address space and then memory gets fragmented
I think.

@komh commented on GitHub (Feb 8, 2023):

It was a high-memory problem, that is, some DLLs are not enabled to use high-memory. Therefore, gcc could not allocate memory in a high-memory heap.

I've fixed this by using DLLs provided by rpm.

However, it would be better to make gcc to use high-memory regardless of heap voting.
