You said you thought you might have, but you didn't confirm it: you didn't run the test program I pointed you at, or run the file command on e.g. your system's copy of ld. Also we don't know whether that toolchain you're using targets mipsel or mipseb. And the only thing you've said in this list is that you thought it was a floating point problem. My Qemu/mipsel system is currently acting up; I've still not got a big-endian system running here, but would hope to have one in a few days. Could anybody comment on the preparedness of the MIPS port for tweak for mipseb: it looks to me as though it's mostly RTL stuff. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

Could anybody comment on the preparedness of the MIPS port for tweak for mipseb: it looks to me as though it's mostly RTL stuff. The compiler and RTL appear to build OK for MIPS (big-endian), giving me a cross compiler which describes itself as expected and a native compiler which looks OK from the outside. I've made no attempt as yet to run the native compiler either on a real system or on a Qemu emulation. http://wiki.lazarus.freepascal.org/Native_MIPS_Systems#Big-endian_subarchitecture -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

When building the crosscompiler try adding CROSSOPT=-Cfsoft. The same argument(-Cfsoft) should be specified when building a program with the crosscompiler afterwards. -Cf sets the FPU type, which by default is set to mips32. soft sets it to softfpu ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
