vbcc is a highly optimizing portable and retargetable ISO C compiler. It supports ISO C according to ISO/IEC 9899:1989 and a subset of the new standard ISO/IEC 9899:1999 (C99).

This is the support site for Amiga (AmigaOS, MorphOS) and Atari (TOS, MiNT, Jaguar).

04-Oct-2019: vbcc 0.9g release.
Changes since last release:
  • Implemented hash table with a default size of 1000. Can be controlled by -hash-size=.
  • Fixed bug with recursive struct definitions.
  • Fixed bug with C99 designated initializers.
  • Fixed C99 initializations of const objects.
  • Fixed bug with mixed dynamic initializations.
  • Fixed bug with partially initialized structs (C99).
  • Addded __noinline attribute.
  • m68k: General improvements of code generation.
  • m68k: Use ASR-sequence for signed division with a power of two.
  • m68k: Fixed peephole bug.
  • m68k: New attribute __fp0ret, to force float-return in fp0, disregarding a -no-fp-return option.
  • m68k: Fixed bug with unsigned short array indexes > 32767.
  • m68k: Allow 16-bit multiplication.
  • m68k: Fix for possible register clobbering in PUSH loops going up.
  • m68k: Avoid using the same reqister for Dr:Dq in DIV?L.L instructions.
  • m68k: Fixed pointer differences in 16-bit int backend (vbccm68ks).
  • m68k: Fixed bug with shiftisdiv on big-endian hosts.
  • PPC: Optimized memcmp() in vclib and as assembler-inline.
  • vclib: Fixed snprintf() and vsnprintf() for sizes exactly matching the source.
  • vclib atari: Made gem.h compile without warning in ANSI/C89 mode.
  • vclib kick13: Support for 16-bit int. New config files.
  • vclib kick13: Workaround for IEEE single to double precision conversion in mathieeedoubtrans.library.
  • Fixed some kick13 clib headers.

In such a complex project there will of course be bugs. Most, especially the serious, bug fixes will be available immediately as a patch. The rest comes with the next release, or by request from the author (see below).
Downloading vbcc 0.9g.

You need to pick the appropriate binary archive for your host platform. Then you can add as many target archives as you need.

Example: If you own a Pegasos running MorphOS and would like to develop programs for MorphOS and AmigaOS/68k, you have to pick the vbcc_bin_morphos archive for the binaries as well as the target archives vbcc_target_ppc-morphos and vbcc_target_m68k-amigaos. Install the binary archive first, using the provided Amiga installer, then add the targets.

The PowerUp and WarpOS binary archives are additional, which means that you need to have a base binary archive already installed. Typically this would be the vbcc_bin_amigaos68k archive.

All target archives are lha-packed, including an Installer script to work under AmigaOS/MorphOS. Target archives in tar.gz format are for Unix/MiNT, without Installer and config files. Target archives in zip format are recommended for Atari TOS systems, which use a different layout due to file system restrictions.

Other host platforms. vbcc is portable enough to run on all operating systems which offer a working ISO-C99 compiler, e.g. BSD, Linux, MacOS and Windows. The latest release source for vasm is available here and for vlink here. The latest vbcc source snapshot may be available here, but it is only rarely updated.

This release's vbcc compiler source is available via the link below.

vbcc_unix_config.tar.gz Default config files for all targets with Unix installation paths.

Installation procedure for AmigaOS/MorphOS: Just click the Install icon. Or refer to chapter 1.3.3 of the documentation for a manual installation.

Installation procedure for MiNT: Refer to the Unix installation instructions in chapter 1.3.1 of the vbcc manual. You may want to download the Unix default config files from above.

Please support vbcc by contacting the authors if you find any bugs or problems. Supporting eight different architectures makes testing extremely time consuming, so this release is probably not free of bugs.

For problems with the compiler core contact Dr. Volker Barthelmann (vbemail), and for Amiga/Atari-specific problems, including assembler, linker, startup-codes and linker-libraries, contact Frank Wille (fwemail).
