Compile Error on piSNES

[shadow128]

Hello @ll,

today I tried to install RetroPie and wanted to compile several emu’s. But on piSNES I’ll got the following compile error:

gcc -I/usr/include -I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I /opt/vc/include/interface/vmcs_host/linux  -c -D_ZAURUS -O3 -march=armv6 -mfpu=vfp -mfloat-abi=hard -ffast-math -fstrict-aliasing -fomit-frame-pointer  -I/usr/include -I/usr/include/SDL -I. -Iunzip -Isdl -I/usr/include/glib-2.0 -I/usr/lib/arm-linux-gnueabihf/glib-2.0/include -D__linux -DZLIB -DVAR_CYCLES -DCPU_SHUTDOWN -DSPC700_SHUTDOWN -fpermissive -Wno-write-strings  -DSPC700_C  -DUNZIP_SUPPORT  -DNO_INLINE_SET_GET unzip/unshrink.c -o unzip/unshrink.o

Does anyone know that failure and how to solve it?

On cimpiling jzintv I’ve a similar failure on compiling :-/

/usr/bin/ld: speed/speed.o: undefined reference to symbol 'floor@@GLIBC_2.4'
//lib/arm-linux-gnueabihf/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:91: recipe for target '../bin/jzintv' failed
make: *** [../bin/jzintv] Error 1

edit:
UAE4ALL also same problem:

/usr/bin/ld: src/m68k/uae/fpp.o: undefined reference to symbol 'tan@@GLIBC_2.4'
//lib/arm-linux-gnueabihf/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:122: recipe for target 'uae4all' failed
make: *** [uae4all] Error 1

No one has an idea for solving that problem?
Is there a package on my raspi missing?

Thanks in advance,

I got the same problem while installing my retropie.
It says after the source-based-installation:

– cannot successfull compile pisnes
– cannot successfull compile jsintv
– cannot succussfull compile uae (amiga emulator)

do i have to update my firmware or anything else?

I ran in this problem with piSNES as well. Here is how I fixed it:

Navigate to the source folder:
/opt/retropie/emulators/pisnes
Edit the Makefile:
Find the line starting with “LDLIBS=”
Add to the end of this line depending on the error received
Example: if the error was about libm.so.6, make sure it has
“-lm” so the compile command knows to add the libm library.
or if it was for librt, add “-lrt”.
Save the Makefile
Compile again:
sudo make

It should compile at this point, or complain about another library. If it does, simply repeat these steps, substituting the new library.

This only corrects the symptoms. I don’t know why the makefile is not generated with the correct libraries.

Great! Thanks for your help!!

Maybe we can collect all failure makefiles with the correct command?

For piSNES I needed the following commands at the end of the LDLIBS-Line:

-lrt -lm -lasound
