Re: [GEM-dev] single object compilation questions: Symbol not found: __ZN7GemBase14beforeDeletionEv

Ok, I figured out what was wrong by going through a related issue on the pd-list. Details are on the github issue.

Cheers,

Hello,

I compiled a simple pix object and can't get pd to load it. (latest Pd test7 from upstream/master compiled for 32bit in OSX 10.11.6...)

I get this error that I don't understand on pd log :

/Users/federicocamarahalac/Documents/fd_lib/pix_fft/pix_fft.pd_darwin:
dlopen(/Users/federicocamarahalac/Documents/fd_lib/pix_fft/pix_fft.pd_
darwin,
10): Symbol not found: __ZN7GemBase14beforeDeletionEv
  Referenced from: /Users/federicocamarahalac/
Documents/fd_lib/pix_fft/pix_fft.pd_darwin
  Expected in: flat namespace
 in /Users/federicocamarahalac/Documents/fd_lib/pix_fft/pix_fft.pd_darwin

This is the compilation:

g++ -DPD -I "/usr/local/include/pd" -I "/Users/federicocamarahalac/Documents/Gem/src"
-DUNIX
-DMACOSX -I /sw/include -Wall -Wextra -Wshadow -Winline -Wstrict-aliasing
-O3 -ffast-math -funroll-loops -fomit-frame-pointer -arch i386 -o
pix_fft.o -c pix_fft.cpp

And the linking:

g++ -undefined suppress -flat_namespace -bundle -arch i386
-o pix_fft.pd_darwin pix_fft.o /usr/local/lib/libfftw3f.a

After compiling, I had no errors and two warnings:

pix_fft.cpp:45:5: warning: field 'm_buffer' will be initialized after
field 'm_bufsize' [-Wreorder]
    m_buffer(0),
    ^
pix_fft.cpp:49:5: warning: field 'm_data' will be initialized after field
'm_bytemode' [-Wreorder]
    m_data(0),
    ^

What am I doing wrong? I opened an issue on github about this as well: #149 https://github.com/umlaeute/Gem/issues/149

I would really appreciate feedback on this, let me know if you need more info.

Thanks,

Fede
