BenJust playing around with the toolchain, attempting to build a mips elf file for Linux. Downloaded and untar’d the latest distribution, and attempting to do a simple hello world:
ellcc/bin/ecc -target mipsel-ellcc-linux hello.c /home/callpop/xcompilers/ellcc/bin/ecc-ld: cannot find /home/callpop/xcompilers/ellcc/bin/../libecc/lib/mipsel/linux/crt1.o: No such file or directory /home/callpop/xcompilers/ellcc/bin/ecc-ld: cannot find /home/callpop/xcompilers/ellcc/bin/../libecc/lib/mipsel/linux/crtbegin.o: No such file or directory /home/callpop/xcompilers/ellcc/bin/ecc-ld: cannot find -lc /home/callpop/xcompilers/ellcc/bin/ecc-ld: cannot find -lcompiler-rt ecc: error: linker command failed with exit code 1 (use -v to see invocation)Everything appears to be in the right place, but it looks like the paths aren’t being constructed properly for the link stage. According to the ellcc/libecc/config/mipsel-linux-eng description, the linker needs to find the runtime libraries in $R/lib/mipsel-linux-eng/, but it looks like it’s only using “mipsel”, which doesn’t exist. Bug? Am I missing something?
Hi Ben,
In version 0.1.28 and earlier, use “-target mipsel-linux-eng”. After version 0.1.29, use “-target mips32r2el-linux”. In both cases, the file in ellcc/libecc/config with the same name as the -target arguments is used to tell the compiler where to find stuff.

BenThanks for the quick reply! I’m now seeing:

Am I missing something in my ecc invocation or installation?
Hi Ben,
That configuration only works with version 0.1.29:
[~] dev% ellcc/bin/ecc -target mips32r2el-linux hello.c [~] dev% file a.out a.out: ELF 32-bit LSB executable, MIPS, MIPS32 rel2 version 1, statically linked, BuildID[sha1]=224a9bbbfdccf5f15573226ba61e78481bf2fc50, not stripped [~] dev% ./ellcc/bin/qemu-mipsel ./a.out hello world [~] dev%
For version 0.1.28 and earlier, use “-target mipsel-linux-eng”:

BenThanks! For some reason I thought I’d downloaded the latest version but must have missed it. That works 🙂
tMHHello everyone!
I use ellcc-0.1.32 version, trying to make ircII, and what I get:
/home/dev/ellcc/bin/ecc -target mips32r2el-linux -I. -I/home/dev/ircii-20131230/include -I/home/dev/ircii-20131230/source/rijndael -pipe -g -O2 -static -DHAVE_CONFIG_H -o mksiginc mksiginc.o -ltermcap -lcrypt
clang-3.9: warning: argument unused during compilation: ‘-g’
/home/dev/ellcc/bin/ecc-ld: cannot find -ltermcap
clang-3.9: error: linker command failed with exit code 1 (use -v to see invocation)
Makefile:342: recipe for target ‘mksiginc’ failed
make: *** [mksiginc] Error 1Please explain, how to fix this “cannot find -ltermcap” thingie ?
Thanks in advance!
-Viktor.
