Hello John/cetoni, Thanks for your replies.
* I tried the stl compatibility layer solution and all goes well until I get the following error: /usr/local/include/ptlib/critsec.h:37:30: fatal error: ext/atomicity.h: No such file or directory It appears that the ptlib library also requires header files that are actually extensions of STL (header files in the folder ext/). These extensions are not defined in ustl, which means this solution will not work. Am I right? * I also tried to build a toolchain including Erik Aagaard Knudsen's libstdc++ for eCos (as described in the file eCos_libstdcxx_compatibility/libstdcxx_compatibility.eak). Here, I encountered the following problem: when configuring GCC (4.3.2.), I get a warning that most of the options such as --enable-languages, --with-gnu-as, --with-gnu-ld, --with-newlib,... are not recognized. When i try to build and install GCC next, I get a whole bunch of assembler messages as follows: /usr/src/gcc-4.3.2/libiberty/regex.c: In function ‘xregerror’: /usr/src/gcc-4.3.2/libiberty/regex.c:8089: warning: implicit declaration of function ‘mempcpy’ /usr/src/gcc-4.3.2/libiberty/regex.c:8089: warning: incompatible implicit declaration of built-in function ‘mempcpy’ /tmp/ccNe5Dme.s: Assembler messages: /tmp/ccNe5Dme.s:5991: Error: r13 not allowed here -- `lsr r3,sp,#3' /tmp/ccNe5Dme.s:6498: Error: r13 not allowed here -- `rsb sp,r3,sp' /tmp/ccNe5Dme.s:6500: Error: r13 not allowed here -- `lsr r0,sp,#3' I think these errors might be caused by a conflict between my native GCC compiler (4.8) and gcc-4.3.2. So I tried to install gcc-4.3.2 on my machine (32-bit ubuntu 12.04) from source (since it's no longer available on aptitude). Here, I encountered a known bug in the linker step (https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/738098). The workaround described here didn't work for me. What do you guys think? 2013/9/17 cetoni GmbH - Uwe Kindler <uwe.kind...@cetoni.de>: > Hi, > > we also had an own library that uses stl and we managed to build it for eCos > uSTL.
