Genode RPC: Handling vector parameters
by 정복득 13 Jul '12

13 Jul '12

Hi, I need to use parameters of std::vector<std::string> type for my RPC program, but it doesn't seem to work. (I want to define a RPC function passing varible number of strings as a parameter. The number of strings is very flexible.) I read about the transferable argument types from the 11.05 release notes. If vector isn't one of the transferable argument type, could you give me an alternative programming tip? Thank you. Best, Bokdeuk Jeong

error with using %lld in Genode::printf or sprintf and including sstream
by 정복득 10 Jul '12

10 Jul '12

Hi, I have two problems with compiling my program. One is that I cannot get correct output with Genode::printf or sprintf for (unsigend) long long values. Below is my code: #include <base/printf.h> #include <stdio.h> #include <sys/types.h> int main() { char test_buf[24]; uint64_t llu_var = 1234567801234ULL; sprintf(test_buf, "%llu", llu_var); Genode::printf("result of test_buf:%s\n", test_buf); Genode::printf("llu_var:%llu\n", llu_var); return 0; } I compiled this with "LIBS += env cxx libc" in target.mk and built it for foc_pbxa9 on QEMU. The result is strange: [init->mytest] result of test_buf:2153943278813471 [init->mytest] llu_var:8212781840017129473 Another one is that I get compilation errors as below: source codes: #include <base/printf.h> #include <stdio.h> #include <sys/types.h> #include <string.h> #include <sstream> using namespace std; template <class T> inline string to_string(const T& t) { stringstream ss; ss << t; return ss.str(); } int main() { int64_t value = 1023456LL; Genode::printf("sstream value:%lld, to_string:%s\n", value, to_string(value).c_str()); return 0; } in target.mk LIBS += stdcxx env cxx libc CC_OPT += -D_GLIBCXX_HAVE_MBSTATE_T error message: /usr/local/genode-gcc/bin/../lib/gcc/arm-elf-eabi/4.6.1/../../../../arm-elf-eabi/lib/libstdc++.a(eh_catch.o): In function '__cxa_begin_catch': (.text.__cxa_begin_catch+0xc0): undefined reference to '__Unwind_Complete' /usr/local/genode-gcc/bin/../lib/gcc/arm-elf-eabi/4.6.1/../../../../arm-elf-eabi/lib/libstdc++.a(eh_catch.o): In function '__cxa_end_catch': (.text.__cxa_end_catch+0x30): undefined reference to '__Unwind_DeleteException' /usr/local/genode-gcc/bin/../lib/gcc/arm-elf-eabi/4.6.1/../../../../arm-elf-eabi/lib/libstdc++.a(eh_catch.o): In function '__cxa_end_catch': (.text.__cxa_end_catch+0xdc): undefined reference to '__Unwind_DeleteException' collect2: ld returned 1 exit status make[2]: *** [mytest] Error 1 Does any one know how to fix these? Thanks.

Is it feasible to maintain a list of platforms(boards) and CPUs that are supported by genode and by which kernel on the website or the github repo?

I saw this thread in the l4-hackers mailing list: http://os.inf.tu-dresden.de/pipermail/l4-hackers/2012/005403.html Could you please answer the same questions regarding drivers in genode. Is it the same way as in L4Re?

Filter platforms in 'run_genode_until'
by Martin Stein 30 May '12

30 May '12

Currently i often run tests that are executable in qemu only on certain platforms but shall be build through the scripts for others as well to do testing on hardware. Would it be nice to let 'run_genode_until' filter out platforms that are not supported autonomously, instead of redundantly guard it via "if have spec" lists in any test? Greets, Martin
