Hi all, For the Dutch among us: de dag die je wist dat zou komen...
Thanks to earlier help I got to build an ARM Linux cross compiler module in fpcup which even compiles fpcup itself (both using trunk and stable starting compiler): opt="-fPIC -dFPC_ARMHF" crossopt="-CpARMV6 -CaEABIHF -CfVFPV2" fpc -g -gl -Tlinux -Parm simple.lpr Question: should I have compiled with -fPIC? Uploaded resulting executable http://ubuntuone.com/0y3yXGcU8fEXR6OTMyvfGN The program: program simple; begin writeln('hello'); end. Relevant fpc.cfg snippet: #IFDEF CPUARM #IFDEF LINUX -CpARMV6 -CaEABIHF -CfVFPV2 -FDC:\development\cross\bin\arm-linux\ -XParm-linux- -Xd -FlC:\development\cross\lib\arm-linux\ -Xr/usr/lib #ENDIF #ENDIF However, running the resulting binary on my virtual Raspbian fails with a segmentation fault. Running under gdb gives (gdb) run Starting program: /root/simple Program received signal SIGSEGV, Segmentation fault. 0x0002b6e4 in SYSTEM_$$_ARRAYSTRINGTOPPCHAR$array_of_ANSISTRING$LONGINT$$PPCHAR () (gdb) bt #0 0x0002b6e4 in SYSTEM_$$_ARRAYSTRINGTOPPCHAR$array_of_ANSISTRING$LONGINT$$PPCHAR () #1 0x00008124 in _start () On the raspbian (which is built on hardfloat), file gives simple: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.0.0, not stripped Compare with system-provided binary: file /usr/bin/yes /usr/bin/yes: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xf2df9a56df5c7b5490f7dba10f2163acb8971fce, stripped Question: should I be worried about the GNU/Linux 2.0.0 above? ldd simple not a dynamic executable I've run readelf -a simple uploaded to http://ubuntuone.com/1cAX24nbcPkGo05fFWDbOr readelf -a /usr/bin/yes uploaded to http://ubuntuone.com/6FD65xgakyE9eZOIme2z47 Question: what steps should I take now?
