Re: [fpc-pascal] opening a serial port in a dll called from dot net fails

Perhaps it is a solution to put the SerOpen in a thread created by FPC and signal that thread from your dot-net-called function. Nope, I tried, same error.

[fpc-pascal] MachO $indirect symbols
When compiling for aarch64 with fpc 3.3.1 on macOS 14.2, I notice some new entries in the Mach-O symbol table of the produced executable, e.g. apart from SegmentName = __DATA_CONST SectionName = __const SymbolName = _VMT_$SYSTEM_$$_TOBJECT n_type = 15 there is now also an entry SegmentName = __DATA_CONST SectionName = __const SymbolName = _VMT_$SYSTEM_$$_TOBJECT$indirect n_type = 15 etcetera. I don't know if the new entries are specific for aarch64, for fpc 3.3.1 or for the linker and assembler used. Also the segment name seems to have changed from __DATA to __DATA_CONST. Just wondering what's behind this. Regards, Adriaan van Os ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
