[pHash-support] 2 compilation errors

[Ricky Huang]

Hello all,

I am currently running an amd64 based FreeBSD 9.0.  While compiling the pHash-0.9.6 I came across the following compilation errors:

Build with: 
  # ./configure --enable-video-hash=no --enable-audio-hash=no
  # make

I get
  pHash.cpp:44: error: 'HW_AVAILCPU' was not declared in this scope

My workaround was to run "sysctl hw.ncpu" on the command line, edit src/pHash.cpp, and replace HW_AVAILCPU with that value.

---

After the above is fixed, I get the following error when I "make"

libtool: link: g++ -O2 -ffast-math -O3 -o .libs/test_texthash test_texthash.o  -L/usr/local/lib ../src/.libs/libpHash.so -lpng /usr/local/lib/libjpeg.so /usr/local/lib/libfftw3.so -lm -Wl,-rpath -Wl,/usr/local/lib
../src/.libs/libpHash.so: undefined reference to `pthread_create'

My workaround for the above is to run configure like the following: ./configure --enable-video-hash=no --enable-audio-hash=no LDFLAGS='-lpthread'


Question are:
1)  Is HW_AVAILCPU something available in FreeBSD?  Am I missing some header files?
2)  Shouldn't the requirement for pthread library be part of the configure and not something I have to provide by hand?



Thanks!
