Hi, I am currently using osg statically and cross-platform. I have been pretty happy with how it worked out but have recently run into problems with certain plugins. Freetype works fine but png or jpeg does not with VS2008.
I do the usual USE_OSGPLUGIN(png); and am also setting the path to the libs (just like with freetype). I get the following unresolved symbol linker problems. Code: Linking... osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_get_io_ptr osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_destroy_write_struct osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_write_end osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_write_image osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_write_info osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_IHDR osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_compression_level osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_write_fn osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_create_info_struct osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_create_write_struct osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_destroy_read_struct osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_get_channels osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_read_end osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_read_image osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_get_rowbytes osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_read_update_info osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_gamma osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_get_gAMA osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_packing osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_tRNS_to_alpha osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_get_valid osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_gray_1_2_4_to_8 osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_palette_to_rgb osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_swap osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_get_IHDR osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_read_info osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_sig_bytes osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_read_fn osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_check_sig osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_set_error_fn osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_get_error_ptr osgdb_png.lib(ReaderWriterPNG.obj) : error LNK2001: unresolved external symbol _png_create_read_struct Unfortunately I do not quite understand the USE_OSGPLUGIN macro and am therefore a bit stuck here. Is there something obvious I am missing? How does this macro include symbols statically from the plugins? Help very much appreciated ;) Thank you!
