I ran into an error saying line 235 of my Makefile has error:

make[4]: Leaving directory `/opt/home/root/native-upstream/native_client/tools/SRC/glibc/wctype'
make  subdir=manual -C manual ..=../ subdir_lib
make[4]: Entering directory `/opt/home/root/native-upstream/native_client/tools/SRC/glibc/manual'
Makefile:235: *** mixed implicit and normal rules.  Stop.
make[4]: Leaving directory `/opt/home/root/native-upstream/native_client/tools/SRC/glibc/manual'
make[3]: *** [manual/subdir_lib] Error 2
make[3]: Leaving directory `/opt/home/root/native-upstream/native_client/tools/SRC/glibc'
make[2]: *** [all] Error 2
make[2]: Leaving directory `/opt/home/root/native-upstream/native_client/tools/BUILD/build-glibc32'
make[1]: *** [BUILD/stamp-glibc32] Error 2
make[1]: Leaving directory `/opt/home/root/native-upstream/native_client/tools'
make: *** [build-with-glibc] Error 2

But I don’t know which Makefile has this error, there are tons of Makefiles in my project:

#  find . -name Makefile
./tools/Makefile
./tools/BUILD/.gcc-extra-build-cloog-ppl/doc/Makefile
./tools/BUILD/.gcc-extra-build-cloog-ppl/Makefile
./tools/BUILD/.gcc-extra-build-cloog-ppl/test/Makefile
./tools/BUILD/.gcc-extra-build-gmp/printf/Makefile
./tools/BUILD/.gcc-extra-build-gmp/doc/Makefile
./tools/BUILD/.gcc-extra-build-gmp/tests/Makefile
./tools/BUILD/.gcc-extra-build-gmp/tests/devel/Makefile
...

So I would like to print line 235 of each Makefile to find out who is the culprit, something like:

./tools/Makefile: 235: $(objpfx)c++-types-check.out: $(check-data) scripts/check-c++-types.sh
./tools/BUILD/.gcc-extra-build-cloog-ppl/doc/Makefile: 235: ifneq (,$(check-data))
./tools/BUILD/.gcc-extra-build-cloog-ppl/Makefile: 235: $(objpfx)c++-types-check.out:
./tools/BUILD/.gcc-extra-build-cloog-ppl/test/Makefile: 235: endif
./tools/BUILD/.gcc-extra-build-gmp/printf/Makefile: 235:
./tools/BUILD/.gcc-extra-build-gmp/doc/Makefile: 235:
./tools/BUILD/.gcc-extra-build-gmp/tests/Makefile: 235: #   Master Makefile for the GNU C library
./tools/BUILD/.gcc-extra-build-gmp/tests/devel/Makefile: 235:

Is there any way to do this?

    It looks like the problem is in /opt/home/root/native-upstream/native_client/tools/SRC/glibc/manual/Makefile, given that the line immediately before the error says it’s entering that directory:

    make[4]: Entering directory `/opt/home/root/native-upstream/native_client/tools/SRC/glibc/manual'
Makefile:235: *** mixed implicit and normal rules.  Stop.

    That said, there are a few ways you could find line 235 of each Makefile. People have already pointed out awk and sed solutions. If you want the filename as well, a quick and easy solution is to use grep:

    find . -name Makefile -print0 | xargs -0 grep -nH $ | grep :235:

    The find command finds all files named Makefile, printing them out null-delimited (so that you don’t have problems if there are files with spaces in their names). xargs passes those filenames to grep. grep -nH prints the filename and line number for every matching line; the $ as the pattern ensures that every line matches (it matches the end of each line). Then you grep within that for the line number you’re looking for.

    It’s not perfect; you might find a few lines that happen to contain “:235:” in them, but it should be fine for a quick one-off (if you really care, you could use `grep ‘^[^:]*:235:’ to ensure that you only match the line number).
