Hi, i have a problem compiling the ppsspp core. i always get: does anyone knows what i am missing?

Looks like you’re missing libpng-dev or equivalent, but it also looks like you’re building standalone instead of the libretro core.

i added: export PKG_CONFIG_PATH="/usr/lib64/pkgconfig/:/usr/local/lib64/pkgconfig/" that solved the missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR error. Now i get a spirv error: spirv_cross.cpp:(.text+0x24c5): undefined reference to spirv_cross::ParsedIR::unset_decoration(spirv_cross::TypedID<(spirv_cross::Types)0>, spv::Decoration)' /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: lib/libspirv-cross-core.a(spirv_cross.cpp.o): in functionspirv_cross::SPIRType& spirv_cross::Compiler::set<spirv_cross::SPIRType>(unsigned int)’: spirv_cross.cpp:(.text.ZN11spirv_cross8Compiler3setINS_8SPIRTypeEJEEERT_jDpOT0[ZN11spirv_cross8Compiler3setINS_8SPIRTypeEJEEERT_jDpOT0]+0x30): undefined reference to spirv_cross::ParsedIR::add_typed_id(spirv_cross::Types, spirv_cross::TypedID<(spirv_cross::Types)0>)' /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: lib/libspirv-cross-core.a(spirv_cross.cpp.o): in functionspirv_cross::SPIRExpression& spirv_cross::Compiler::set<spirv_cross::SPIRExpression, char const (&) [1], unsigned int&, bool>(unsigned int, char const (&) [1], unsigned int&, bool&&)’: spirv_cross.cpp:(.text.ZN11spirv_cross8Compiler3setINS_14SPIRExpressionEJRA1_KcRjbEEERT_jDpOT0[ZN11spirv_cross8Compiler3setINS_14SPIRExpressionEJRA1_KcRjbEEERT_jDpOT0]+0x3e): undefined reference to spirv_cross::ParsedIR::add_typed_id(spirv_cross::Types, spirv_cross::TypedID<(spirv_cross::Types)0>)' /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: lib/libspirv-cross-core.a(spirv_cross.cpp.o): in functionspirv_cross::SPIRVariable& spirv_cross::Compiler::set<spirv_cross::SPIRVariable, unsigned int&, spv::StorageClass, int>(unsigned int, unsigned int&, spv::StorageClass&&, int&&)’: spirv_cross.cpp:(.text.ZN11spirv_cross8Compiler3setINS_12SPIRVariableEJRjN3spv12StorageClassEiEEERT_jDpOT0[ZN11spirv_cross8Compiler3setINS_12SPIRVariableEJRjN3spv12StorageClassEiEEERT_jDpOT0]+0x3e): undefined reference to `spirv_cross::ParsedIR::add_typed_id(spirv_cross::Types, spirv_cross::TypedID<(spirv_cross::Types)0>)’ collect2: Fehler: ld gab 1 als Ende-Status zurück make[2]: *** [CMakeFiles/PPSSPPSDL.dir/build.make:583: PPSSPPSDL] Fehler 1 make[1]: *** [CMakeFiles/Makefile2:530: CMakeFiles/PPSSPPSDL.dir/all] Fehler 2 make: *** [Makefile:130: all] Fehler 2

Thank you

Like I said, I’m pretty sure you’re not compiling the libretro core, but rather the standalone PPSSPP application, which I’m not familiar enough with to provide support.

#5

sorry… i thought with: ./b --libretro i am building the libretro core only how to build it the correct way? (i cannont find it)

#6

It looks like the libretro core is built via the static Makefile inside the libretro directory.

#7

Hi, this night i tried a complete build with my standard script: ./libretro-build.sh ./retroarch-build.sh ./libretro-config.sh ./libretro-super.sh ./retrolink.sh ./libretro-install.sh ./libretro-fetch.sh retroarch ./libretro-build-database.sh cd retroarch make install and got this result: spirv_glsl.cpp:(.text._ZN11spirv_cross12CompilerGLSL12emit_glsl_opEjjjPKjj+0x1151): undefined reference to spirv_cross::ParsedIR::increase_bound_by(unsigned int)' /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: ../ext/SPIRV-Cross/spirv_glsl.o: in functionspirv_cross::CompilerGLSL::emit_instruction(spirv_cross::Instruction const&)’: spirv_glsl.cpp:(.text._ZN11spirv_cross12CompilerGLSL16emit_instructionERKNS_11InstructionE+0x3d6f): undefined reference to spirv_cross::ParsedIR::add_typed_id(spirv_cross::Types, spirv_cross::TypedID<(spirv_cross::Types)0>)' /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: spirv_glsl.cpp:(.text._ZN11spirv_cross12CompilerGLSL16emit_instructionERKNS_11InstructionE+0x6685): undefined reference tospirv_cross::ParsedIR::add_typed_id(spirv_cross::Types, spirv_cross::TypedID<(spirv_cross::Types)0>)’ collect2: Fehler: ld gab 1 als Ende-Status zurück gmake: *** [Makefile:444: ppsspp_libretro.so] Fehler 1 cp “ppsspp_libretro.so” “/usr/local/src/libretro-super/dist/unix/ppsspp_libretro.so” cp: der Aufruf von stat für ‘ppsspp_libretro.so’ ist nicht möglich: Datei oder Verzeichnis nicht gefunden i think spirv-tools ist somewhere broken (i use gentoo and try to reemerge it)

#8

Hi, i got much further uninstalling the spirv-tools. the old PNG_LIBRARY PNG_PNG_INCLUDE_DIR errors doesn´t matter. it useses the png library included in the ppsspp source instead. now i get: /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/…/…/…/…/x86_64-pc-linux-gnu/bin/ld: /usr/lib/libSDL2.so: error adding symbols: file in wrong format collect2: Fehler: ld gab 1 als Ende-Status zurück make[2]: *** [libretro/CMakeFiles/ppsspp_libretro.dir/build.make:178: lib/ppsspp_libretro.so] Fehler 1 make[1]: *** [CMakeFiles/Makefile2:2562: libretro/CMakeFiles/ppsspp_libretro.dir/all] Fehler 2 make[1]: *** Es wird auf noch nicht beendete Prozesse gewartet… /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/…/…/…/…/x86_64-pc-linux-gnu/bin/ld: /usr/lib/libSDL2.so: error adding symbols: file in wrong format collect2: Fehler: ld gab 1 als Ende-Status zurück make[2]: *** [CMakeFiles/PPSSPPSDL.dir/build.make:583: PPSSPPSDL] Fehler 1 make[1]: *** [CMakeFiles/Makefile2:530: CMakeFiles/PPSSPPSDL.dir/all] Fehler 2 make: *** [Makefile:130: all] Fehler 2 which is realy strange. because in /usr/lib are the 32bit Libraries. it should use /usr/lib64 for linking the 64bit Libraries. (i have a multilib system) think i have to check the gentoo forums for that. Thank you for the support :slight_smile:

#9

Finaly i made it. it´s so simmple: in the build script add: . /etc/portage/make.conf and ppsspp core is building fine :slight_smile:
