pjrc-8051 README
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This port uses the PJRC 87C52 development system and the SDCC toolchain.
|
|
|
|
The PJRC 87C52 development system can be obtained from http://www.pjrc.com/.
|
|
|
|
The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
|
|
testing has been performed using verison 2.6.0 of the SDDC toolchain.
|
|
|
|
Building the SDCC toolchain
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The SDCC toolchain is built with the standard configure/make/make install
|
|
sequence. However, some special actions are required to generate libraries
|
|
compatible with this build. First start with the usual steps
|
|
|
|
download
|
|
unpack
|
|
cd sdcc
|
|
./configure
|
|
make
|
|
|
|
But before installing, we need to apply a patch to the SDCC 2.6.0 source.
|
|
WARNING: This patch is specific to the particular combination of CFLAGS
|
|
that are used in the compilation. If you change Make.defs, then you will
|
|
likely have to change the patch as well.
|
|
|
|
Apply sdcc-2.6.0.patch
|
|
cd sdcc/device/lib
|
|
make model-mcs51-stack-auto
|
|
|
|
Then
|
|
|
|
cd sdcc
|
|
make install
|
|
|
