[Description Nick Novikov 2017-01-09 20:21:20 UTC]

Created attachment 459392 [details, diff]
a trivial patch

In file bin/Makefile.am $(MATH_LIB) should be added to AM_LDFLAGS explicitly like in the master version

/usr/lib/gcc/i686-pc-linux-gnu/4.9.4/../../../../i686-pc-linux-gnu/bin/ld: gegl-path-smooth.o: undefined reference to symbol 'sqrt@@GLIBC_2.0'

Hi everybody,

I stumbled over the same issue in the tools directory when compiling version 0.2.0-r2 on aarch64:
+++++
/usr/lib/gcc/aarch64-unknown-linux-gnu/4.9.4/../../../../aarch64-unknown-linux-gnu/bin/ld: img_cmp.o: undefined reference to symbol 'sqrt@@GLIBC_2.17' /lib64/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

I could fix the issue with this patch:

My question is if we should re-open this bug or should I file a new one?

Sorry, I should have said ARM64 instead of aarch64.
