hbmk2 [options] [<script[s]>] <src[s] [.prg|.c|.obj|.o|.rc|.res|.def|.po|.pot|.hbl|@.clp|.d|.ch]>


hbmk2 is an integrated and portable build tool, making it possible to create various types of executable binaries (executable, dynamic library, static library, Harbour portable binary) out of multiple types of source files (C, C++, Objective-C, Harbour, gettext translations, Windows resources). ‘Integrated’ means that a single hbmk2 project file can control all or most aspects of the build process. ‘Portable’ means that a single hbmk2 project file can control the build on all supported OS platforms and across all supported C compilers. It also aims to cover the majority of build tasks via short and simple project files (options). hbmk2 supports pure -non-Harbour- C/C++/Objective-C projects as well. In order to achieve above goals, hbmk2 will autodetect Harbour, C compiler and other required tools, then configure and call them appropriately. hbmk2 allows to extend the types of supported source files via plugins.

Besides building executables, hbmk2 is able to run Harbour scripts (both source and precompiled) directly, and it also features an interactive shell prompt.

Exit codes (“errorlevels”):

  • 0 no error
  • 1 unknown platform
  • 2 unknown compiler
  • 3 failed Harbour detection
  • 5 failed stub creation
  • 6 failed in compilation (Harbour, C compiler, Resource compiler)
  • 7 failed in final assembly (linker or library manager)
  • 8 unsupported
  • 9 failed to create working directory
  • 19 help
  • 10 dependency missing or disabled
  • 20 plugin initialization
  • 30 too deep nesting
  • 50 stop requested
  • <other> when -run option is used, the exit code will be the one returned by the target executable


  • <script> can be:
    <@script> or <script.hbm>: command-line options in file
    <script.hbp>: command-line options in file, it also marks a new build target if specified on the command-line
    <script.hbc>: package configuration file
  • Source filename without extension will load the .hbp file, if such .hbp file exists in current directory. If not, .prg extension will be used.
  • Multiple -l, -L, -i and <script> parameters are accepted.
  • Regular Harbour compiler options are also accepted as is.
    (see them with -harbourhelp option)
  • hbmk.hbc option file in hbmk2 directory is always processed if it exists. On *nix platforms ~/.harbour, /etc/harbour, <base>/etc/harbour, <base>/etc are checked (in that order) before the hbmk2 directory.
  • hbmk.hbm make script in current directory is always processed if it exists.
  • Using forwards slashes is recommended in option values as directory separator, but backslashes are also equally accepted.
  • Filters are accepted in each .hbc line and most options.
    Filters can be combined using ‘&’ (and), ‘|’ (or) operators, negated by ‘!’ operator and grouped by parentheses. Ex.: {win}, {gcc}, {linux|darwin}, {win&!pocc}, {(win|linux)&!watcom}, {unix&mt&gui}, -cflag={win}-DMYDEF, -stop{dos}, -stop{!allwin}
  • Most .hbc lines (libs=, hbcs=, prgflags=, cflags=, ldflags=, libpaths=, instfiles=, instpaths=, echo=) and corresponding command-line parameters will accept macro variables. libpaths= also accepts %{hb_name} which translates to the name of the .hbc file under search.
  • Options accepting macro variables also support command substitution. Enclose command inside “, and, if the command contains space, also enclose in double quotes. Standard output of the command will be used as the value. F.e. “-cflag=`wx-config –cflags`”, or ldflags={unix&gcc}”`wx-config –libs`”.
  • When multiple build target type selection options (-hblib, -hbdyn, etc.) are specified, the first one will be significant, the rest will be silently ignored.
  • Libraries and object files built with/for CA-Cl*pper will not work with any supported platform/compiler.
  • Defaults and feature support may vary by platform/compiler.
  • GNU Make or any C compiler specific make tool and MSYS (on Windows) are not needed to run hbmk2.
  • . (dot) passed as first parameter will enter the interactive Harbour shell.
  • .hb, .hrb or .dbf file passed as first parameter will be run as Harbour script. If the filename contains no path components, it will be searched in current working directory and in PATH. If not extension is given, .hb and .hrb extensions are searched, in that order. .dbf file will be opened automatically in shared mode and interactive Harbour shell launched. Non-standard extensions will be autodetected for source and precompiled script types. Note, for Harbour scripts, the codepage is set to UTF-8 by default. The default core header ‘hb.ch’ is automatically #included. The default date format is the ISO standard: yyyy-mm-dd. The default GT is ‘gtcgi’, unless full-screen CUI calls are detected, when ‘gtwin’ [*] is automatically selected (except for INIT PROCEDUREs).
  • You can use key <Alt+V> in interactive Harbour shell to paste text from the clipboard.
  • Values marked with [*] may be host platform and/or configuration dependent. This help was generated on ‘win’ host platform.
