Problem Solved building roboard lib in DJGPP

2010-01-13T13:04:41+01:00

Please try

gcc -o servo.exe servo.o -L. -lRBIO -lstdcxx

success!

i had to move libstdcxx.a into the lib directory , and then call it with

gcc -o servo.exe servo.o -L. -lRBIO -lstd~1

because of the 8 character file name limit

thank you for all your help and patience , i got it to work off the command line and in RHIDE also , thanks again

and the errors i got seem to indicate that it can find the lib file but that there is a problem

Please try

gcc -o servo.exe servo.o -L. -lRBIO -lstdcxx

Hi
i have been working on it tonight and have an update

i had gotten the file to compile fine but it was bombing out when i would try to link it , and the errors i was getting were that DJGPP could not find the libRBIO.a

so since i had the object file servo.o , i tried to link it on the command line with
GCC -0 servo.exe servo.o libRBIO.a

and the errors i got seem to indicate that it can find the lib file but that there is a problem

libRBIO.a(Rcservo.o):Rcservo.cpp:(.eh_frame+011):undefined reference to '___gxx_personality_V0'
libRBIO.a(common.o):common.cpp:(.eh_frame+011):undefined reference to '___gxx_personality_V0'
libRBIO.a(IO.o):IO.cpp:(.eh_frame+011):undefined reference to '___gxx_personality_V0'
libRBIO.a(PWMDX.o):PWMDX.cpp:(.eh_frame+011):undefined reference to '___gxx_personality_V0'
libRBIO.a(PWM.o):PWM.cpp:(.eh_frame+011):undefined reference to '___gxx_personality_V0'

and it errors out , without creating the EXE file , i am wondering if DJGPP has updated their software ( i have VER v2gnu/gpp442b.zip ), or that i have still not been able to link the library correctly , any help would be great , thanks again

Hi
i have DJGPP downloaded and installed in my RoBoard , i can compile and build standard C files fine , i would like to install the roboard lib and include files so i can compile and build some Roboard programs

i have RoBoIO-src-v1.5b-gcc downloaded and need to know how to set it up before i run the make file make.dj , i have tried a number of ways and have only gotten errors so far

where should i have the libsrc directory when i type make.dj

should i copy the libsrc files into C:\DJGPP\LIB first or should i move the whole directory into the C:\DJGPP\LIB folder , and then type MAKE.DJ

i am guessing i can't just move LIBRBIO.A into the C:\DJGPP\LIB folder

i spent some time trying different things and reading up on DJGPP website , with no luck , when i try to link DJGPP can't find the library , i have tried giving it the libRBIO.a path in the options menu , again without any luck

not sure what i am doing wrong or even if i am on the right track , any help would be great , thanks again
