-====== About this document ======
-For all assembler-based applications, [[MPLAB]] is needed, that's only available for Windows (or Linux via Wine). But there is a solution, described below, with which you can compile asm code with MPASM, a tool that's available not only for Linux, but as well for Macs!
-Thanks to svens for sharing this!
-====== Compiling MIOS on Linux ======
-If you ever tried to compile the MIOS source with gpasm on Linux, you've probably got a lot of errormessages like:
-  svens@deprecated(1033)[0]:./src2$ gpasm main.asm
-  mios_isr.inc:76:Error [103] syntax error
-  mios_isr.inc:77:Error [103] syntax error
-  mios_isr.inc:78:Error [103] syntax error
-  mios_isr.inc:80:Error [103] syntax error
-  mios_isr.inc:81:Error [103] syntax error
-  mios_isr.inc:84:Error [103] syntax error
-  mios_isr.inc:133:Error [103] syntax error
-  mios_isr.inc:138:Error [103] syntax error
-  mios_isr.inc:174:Error [103] syntax error
-  mios_isr.inc:205:Error [103] syntax error
-These errors are caused by a nice Feature from mpasm -- you can pass instructions as Macro argument. Unfortunately, gpasm has (at least right now) no support for this, so i wrote a small quick&dirty script, that changes all these MACROs to the appropriate syntax. To use this script, copy the following files in your mios_v_1_x_src dir:
-replace-macros.sed:
-i;hey emacs, this is -*- asm -*-
-  /^[ \t]*;/b #skip commented line
-  /^\s*\w*\s*MACRO/b #skip macro definitions
-  s/\<BIFSET\s*\([^,]*\)\s*,\s*\([^,]*\),\s*\([^,]*\)\s*,\s*\(.*\)/btfsc \1, \2, \3\n\t\4/g
-  s/\<BIFCLR\s*\([^,]*\)\s*,\s*\([^,]*\),\s*\([^,]*\)\s*,\s*\(.*\)/btfss \1, \2, \3\n\t\4/g
-  s/\<IFSET\s*\([^,]*\)\s*,\s*\([^,]*\),\s*\(.*\)/btfsc \1, \2\n\t\3/g
-  s/\<IFCLR\s*\([^,]*\)\s*,\s*\([^,]*\),\s*\(.*\)/btfss \1, \2\n\t\3/g
-  s/\<IFNEQ\s*\([^,]*\)\s*,\s*\([^,]*\),\s*\(.*\)/cpfseq \1, \2\n\t\3/g
-  s/\<IFLEQ\s*\([^,]*\)\s*,\s*\([^,]*\),\s*\(.*\)/cpfsgt \1, \2\n\t\3/g
-  s/\<IFGEQ\s*\([^,]*\)\s*,\s*\([^,]*\),\s*\(.*\)/cpfslt \1, \2\n\t\3/g
-  s/\<rgoto\>/bra/g
-fix-gpasm.sh:
-  #!/bin/sh
-  for i in src/*.inc src/*.asm src/*.h;do
-      tr -d '\r' < $i|sed -f replace-macros.sed >${i}_ && mv ${i}_ $i
-  done
-Now you can run ./fix-gpasm.sh, which replaces all the problematic macros.
