问题 I compiled Python 2.6.6 with google-perf tools (tcmalloc) library to eliminate some of the memory issues I was having with the default 2.6.5. After getting 2.6.6 going it seems to not work becuase I think having issues with the default 2.6.5 install in Ubuntu. Will none of the binaries installed from the software channel like wxPython and setuptools work properly with 2.6.6. Do these need to be recompiled? Any other suggestions to get it working smoothly. Can I still set 2.6.5 as default

问题 I have a program in Qt creator that compiles and runs fine in a Windows machine.

问题 I have followed some tutorials on the web and created my own kernel. It is booting on GRUB with QEMU succesfully. But I have the problem described in this SO question, and I cannot solve it. I can have that workaround described, but I also need to use global variables, it would make the job easier, but I do not understand what should I change in linker to properly use global variables and inline strings. main.c struct grub_signature { unsigned int magic; unsigned int flags; unsigned int

问题 I'm trying to link a static library to a shared library via a command like g++ -shared obj.o archive.a -o libLib.so But at run time I keep getting unresolved system that should be link at compile time from archive.a. I've tried g++ -shared obj.o -Wl,-Bstatic archive.a -Wl,-Bdynamic -o libLib.so and g++ -shared obj.o -Wl,-whole-archive archive.a -Wl,-no-whole-archive -o libLib.so with no success. I feel like I'm missing something basic here... 回答1: You practically cannot (i.e. should never )
