[LAD] G++ trouble

Hello all, I'm having a strange problem with G++... In one source file 'fb3data.cc', I define arrays like this: const float svcoeff44 [216] = { 1.631996e-03, 6.335480e-02, ... ... }; There are five of these. In 'fbdata3.h' I have extern const float svcoeff44 [216]; extern const float svcoeff48 [216]; extern const float svcoeff88 [216]; ... Finally in 'filtbank3.cc' there is const float *c; switch (fsam) { case 44100: c = cvcoeff44; break; case 48000: c = cvcoeff48; break; ... } Everything compiles without errors or warnings, but the linking step fails: /usr/bin/ld: filtbank3.o: warning: relocation against `svcoeff88' in read-only section `.text' /usr/bin/ld: filtbank3.o: in function `VocFiltbank::init(int)': filtbank3.cc:(.text+0x159): undefined reference to `svcoeff192' /usr/bin/ld: filtbank3.cc:(.text+0x1d3): undefined reference to `svcoeff48' /usr/bin/ld: filtbank3.cc:(.text+0x1e3): undefined reference to `svcoeff96' /usr/bin/ld: filtbank3.cc:(.text+0x1f3): undefined reference to `svcoeff44' /usr/bin/ld: filtbank3.cc:(.text+0x1ff): undefined reference to `svcoeff88' /usr/bin/ld: warning: creating DT_TEXTREL in a PIE collect2: error: ld returned 1 exit status When I put the arrays in 'filtbank3.cc' instead, everything works. Any hints ?? Ciao, -- FA
