If you are using a Squeak trunk image and have VMMaker loaded, you can evaluate "VMMaker updateFromServer; initialize". Then open an inspector on e.g. ObjectMemory or FilePlugin, click the "source" button on the browser, and select "translate to C" or "translate inlined C". The translated C code for each method is displayed interactively. Dave |

Hello, Today I was preparing a new VM from svn sources (trunk) but then, the following happened: gcc -g -O2 -fomit-frame-pointer -DLSB_FIRST=1 -DHAVE_CONFIG_H -DSQUEAK_BUILTIN_PLUGIN -I/home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/bld -I/home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/vm -I/home/casimiro/Softwares/squeak/squeak-svn/platforms/Cross/vm -I/home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm -c -o ADPCMCodecPlugin.o /home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm/intplugins/ADPCMCodecPlugin/ADPCMCodecPlugin.c /home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm/intplugins/ADPCMCodecPlugin/ADPCMCodecPlugin.c:72: error: expected declaration specifiers or ‘...’ before ‘*’ token /home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm/intplugins/ADPCMCodecPlugin/ADPCMCodecPlugin.c:72: error: ‘sqInt’ redeclared as different kind of symbol /home/casimiro/Softwares/squeak/squeak-svn/platforms/Cross/vm/sqMemoryAccess.h:52: note: previous declaration of ‘sqInt’ was here /home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm/intplugins/ADPCMCodecPlugin/ADPCMCodecPlugin.c:73: error: expected declaration specifiers or ‘...’ before ‘(’ token /home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm/intplugins/ADPCMCodecPlugin/ADPCMCodecPlugin.c:74: error: expected declaration specifiers or ‘...’ before ‘(’ token /home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm/intplugins/ADPCMCodecPlugin/ADPCMCodecPlugin.c:75: error: expected declaration specifiers or ‘...’ before ‘(’ token /home/casimiro/Softwares/squeak/squeak-svn/platforms/unix/src/vm/intplugins/ADPCMCodecPlugin/ADPCMCodecPlugin.c:80: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘halt’ |

If you use the old configure script you will get lots of entertaining error messages. Dave |

The only other thing I can suggest is to start with a completely empty build directory before you run configure, and then make sure that you are specifying the right source directory (--src= option to the configure script). I have found cases where my build directory gets messed up, and if I just delete everything and start fresh it works fine. Dave |

Casimiro, don't know if this is news to you but you can use -P or -E as arguments to the compiler to get it to write the pre-processed output to either foo.i (-P) or stdout (-E). Then you can find out which include files are pulled in, etc, and get more info on the problem.

Do not use the source files in platforms/unix/vm/src. If you are building your own plugin or changing the configuration of plugins being built, then it is better to use VMMaker to generate all of the source files into a clean directory. Then when you run configure, you can use the "--src= " command line option to specify the new source directory. When you run make, it will compile your freshly generated source files rather than mixing your newly generated plugin source with the older source and header files in platforms/unix/vm/src. You can think of the generated source files as transient files, like the *.o files produced by a C compiler. The files in the platforms/unix/vm/src/ directory are a snapshot of the generated source files that were used for the last official VM build. But if you are building a VM yourself, it is usually best to just generate your own source files into a clean directory. This will ensure that the generated header and source files are consistent, and and also that that all of your source files were generated by the same version of VMMaker. Dave |
