I'm trying the SDK tutorial at http://www.pdaxrom.org/index.php?showid=35&menuid=1
I tried the newvox sample on my SuSE Linux10(x86) host. I'm using the C750 SDK and it seemed changed a little bit, so I adjusted the commandline provided in tutorial like this: LDFLAGS="-Wl,-rpath-link,/opt/cross/arm/3.4.5-xscale-softvfp/armv5tel-cacko-linux/X11R6/lib" ./configure --host=armv5tel-cacko-linux --build=i686-linux --x-includes=/opt/cross/arm/3.4.5-xscale-softvfp/armv5tel-cacko-linux/X11R6/include --x-libraries=/opt/cross/arm/3.4.5-xscale-softvfp/armv5tel-cacko-linux/X11R6/lib --disable-debug --prefix=/usr/local I'm not sure about the /X11R6/ part because I can't find it in the SDK folder. Anyway, the output is as follows: checking whether the C compiler (gcc -Wl,-rpath-link,/opt/cross/arm/3.4.5-xscale-softvfp/armv5tel-cacko-linux/X11R6/lib) works... yes checking whether the C compiler (gcc -Wl,-rpath-link,/opt/cross/arm/3.4.5-xscale-softvfp/armv5tel-cacko-linux/X11R6/lib) is a cross-compiler... no checking whether we are using GNU C... yes checking whether gcc accepts -g... yes checking for sdl-config... /opt/cross/arm/3.4.5-xscale-softvfp/bin/sdl-config checking for SDL - version >= 1.0.1... no *** Could not run SDL test program, checking why... *** The test program failed to compile or link. See the file config.log for the *** exact error that occured. This usually means SDL was incorrectly installed *** or that you have moved SDL since it was installed. In the latter case, you *** may want to edit the sdl-config script: /opt/cross/arm/3.4.5-xscale-softvfp/bin/sdl-config configure: error: *** SDL version 1.0.1 not found! It seems like the compiler is working. But it says "no" on: checking whether the C compiler (gcc -Wl,-rpath-link,/opt/cross/arm/3.4.5-xscale-softvfp/armv5tel-cacko-linux/X11R6/lib) is a cross-compiler. Am I using the wrong parameters? Also, do I need to compile SDL before compiling newvox? The SDK installation page says the SDK contains SDL, though. |

better tutorials:
http://www.oesf.org/index.php?title=Pdaxro...oss_Compilation http://www.oesf.org/index.php?title=Pdaxro...te_An_Ipk_Howto The X11 headers and libs are together with the other headers and libs so you shouldn't have to set the x includes and library path |

Thanks for the hints. Will try next Monday.
BTW, I'm thinking about having a Linux on my laptop(so I can try this at home). Is Debian the best choice? I only want to do pdaXrom cross-compiling and maybe some PIM apps. Is a Live-CD a good idea? (My laptop doesn't have much free disk spaces) |

It is built for just this. |

(My laptop doesn't have much free disk spaces) Why not use the pdaXrom X86 live CD? It is built for just this. I end up using the pdaXrom VMWare image. For me, It's convenient than the LiveCD because I can take the development environment with me between office and home. (I copied the whole image files to a 512M USB thumb drive.) Many thanks to pgas! I successfully built my first Z application (hello) following the new guide you suggested. I'm still trying to build other apps to learn more before I can build something really useful. |

I think this is where my problem is--the program is still using gcc instead of armv5tel-cacko-linux-gcc. What should I do to fix this? |
