In the meantime I have the Ethernet library (for ENC28J60) and a simple webserver working on another STM32 board, using the STM Library SPI and GPIO config commands and pure C. Now I still want to port this to the Maple, I think my biggest issue is really not understanding the C/C++ mix, because the existing library consists of a bunch of .c and .h files and I guess that is where it falls down. But I'll let you know when I have it uploaded.

In general, you can mix and match c/c++ files if: A) all your c code declarations are wrapped in an appropriate <pre><code>#ifdef __cplusplus extern "C" { #endif</code></pre> blocks (see any random .h file in libmaple) B) you are using the correct c++ compiler (arm-none-eabi-g++ not arm-none-eabi-gcc). You can see in a regular libmaple command line build how the compiler is treating C and C++ files with different compilers. If you provide a bit more information about your build environment, and link to sources, we can probably track down where its going wrong. You might have success just by changing the C files that include wirish to .cpp files. mikep on "Porting Arduino Library - Compile Errors" http://forums.leaflabs.com/topic.php?id=908#post-5603 Sat, 09 Jul 2011 13:51:02 +0000 mikep 5603@http://forums.leaflabs.com/ Hi All, I am trying to port the Arduino Ethernet library (for ENC28J60) to the Maple. The Arduino library is located here: <a href="http://blog.thiseldo.co.uk/?p=570" rel="nofollow">http://blog.thiseldo.co.uk/?p=570</a> I did all the type conversions (unit8_t -> uint8 etc.) and took out the avr-specific includes, but now I am at a point where I get some cryptic (to me at least) compile errors as soon as I try to include "wirish.h" The errors are like this: <code> from C:\Users\Michael\Documents\MapleIDE\libraries\EtherShield28J60_062011\enc28j60.c:21: C:\Program Files (x86)\Leaflabs_Maple\maple-ide-0.0.11\hardware\leaflabs\cores\maple/boards.h:118: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'boardUsesPin' from C:\Users\Michael\Documents\MapleIDE\libraries\EtherShield28J60_062011\enc28j60.c:21: C:\Program Files (x86)\Leaflabs_Maple\maple-ide-0.0.11\hardware\leaflabs\cores\maple/io.h:201: error: expected ';', ',' or ')' before '=' token from C:\Users\Michael\Documents\MapleIDE\libraries\EtherShield28J60_062011\enc28j60.c:21: C:\Program Files (x86)\Leaflabs_Maple\maple-ide-0.0.11\hardware\leaflabs\cores\maple/wirish_math.h:56: error: conflicting types for 'random' C:\Program Files (x86)\Leaflabs_Maple\maple-ide-0.0.11\hardware\leaflabs\cores\maple/wirish_math.h:47: note: previous declaration of 'random' was here from C:\Users\Michael\Documents\MapleIDE\libraries\EtherShield28J60_062011\enc28j60.c:21: C:\Program Files (x86)\Leaflabs_Maple\maple-ide-0.0.11\hardware\leaflabs\cores\maple/HardwareSPI.h:71: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'HardwareSPI' </code> This goes on for a while, basically most of the files include'd in wrish.h generate a similar error. Line 21 in enc28j60.c is this: <code> #include "wirish.h" </code> What am I doing wrong? These low-level files I am working on are C files that are used by the Ethernet.cpp file. Can wirish not be included in a C file? Is there any better way to troubleshoot this and get to the bottom of this error? Thank you, Mike
