I got the same error and the -fpermissive did the trick. I manage to index a website and the search is working fine.

Still there are lots of warnings during the build. Most 3 warnings repeating all the time:

/usr/include/features.h:376:4: warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp] # warning _FORTIFY_SOURCE requires compiling with optimization (-O) ^~~~~~~

defaults.cc:2830:1: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]

db_int.h:91:28: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] #define SSZA(name, field) ((int)&(((name *)0)->field[0])) ^

Adding -fpermissive to CXXFLAGS helps. But its a hack, and I cannot see consequences at this time. Try it.

Simply edit one line in yours PKGBUILD

CFLAGS=-Wno-narrowing CXXFLAGS=-Wno-narrowing ./configure --prefix=/usr \

to this one:


CFLAGS=-Wno-narrowing CXXFLAGS="-Wno-narrowing -fpermissive" ./configure --prefix=/usr \

It helps. If it works without glitches, write here, and I make a patch.

Building gives this error:
