LDSO Question
by Sam Kerr 23 Mar '11

23 Mar '11

Hi All, I have been trying to work with the LDSO library and have been having some more package. I am running Genode on top of Pistachio. I created a bootable image with the LDSO module, but when I start the disk, I get the following error message from LDSO: [init -> ldso] Starting ldso ... [init -> ldso] realloc - not yet implemented 04804002 pf @ fffffffc, ip=00042ecd --- "KD# user touches kernel area" --- --------------------------------- (eip=f010c342, esp=f01163c7) --- It's clear that realloc is not implemented, but is this provided in some other file? How do I work with the LDSO code? -Sam Kerr

Base capabilities
by Daniel Waddington 22 Mar '11

22 Mar '11

Hi, I'm trying to put in some temporary feature in Genode to set the affinity of threads. In Genode the scheduler capability (L4_BASE_SCHEDULER_CAP) doesn't seem to be passed from the core to the children. Is there any obvious way to do this with the existing Genode implementation - we can hack up a solution but I wanted to check first. Thanks Daniel

by Daniel Waddington 17 Mar '11

17 Mar '11

Hi, I'd like to be able to use the native Fiasco.OC L4re APIs (actually to set thread affinity) from within my Genode application. Its not clear to me how to set up the target.mk to do such things. Any advice? Daniel

Use of malloc primitives in Genode
by Amadeo Cuadrado 16 Mar '11

16 Mar '11

Hello, When I try to build the app below in Genode, the following linking error happens: main.o: In function `main': .../main.cc:6: undefined reference to `malloc(unsigned int)' .../main.cc:8: undefined reference to `free(void*)' What am I missing here? Thanks! Amadeo :::::::::::::: main.cc :::::::::::::: #include <stdlib.h> #define N 10 int main(void) { int *v = (int *) malloc(N*sizeof(int)); for (int i=0; i<N; i++) v[i] = i; free(v); } :::::::::::::: target.mk :::::::::::::: TARGET = foo SRC_CC = main.cc LIBS = cxx env mini_c

LDSO main()
by Sam Kerr 15 Mar '11

15 Mar '11

Hello all, I am trying to do some work with dynamic linking and saw there is an LDSO folder with a main() function. I would like to try running this on top of Pistachio. However, I cannot get the main() function to run. I have tried just including the module in the grub.conf file to no avail. Does anyone have some guidance on how to boot the LDSO test function? -Sam Kerr

Problems with socket()
by Александр Домо 15 Mar '11

15 Mar '11

Hello! I'm writing a network application using libc, lwip, libc_lwip, and libc_lwip_nic_dhcp. But when I call socket(SOCK_STREAM), it hangs somewhere in lwip_socket(). Maybe it has something to do with the lwip tcp thread, but I'm not sure. What else should I check for? Thanks.
