Hi all,
Now I have the source code of microwindows ( version is
0.89pre9, download from ftp.microwindows.org
<ftp://ftp.microwindows.org/> ), it use stdlibc.
And now I want to use uclibc instead of stdlibc, I edit the
Arch.rules file mainly like this:
COMPILER = /uClibc-0.9.19/extra/gcc-uClibc/i386-uclibc-gcc
CFLAGS += --uclibc-use-build-dir ¨CWall $(OPTIMATION)
LDFLAGS += --uclibc-use-build-dir ¨Cs -Wl,-warn-common
#the above flags reference to the ../test/Rules.mak of uclibc
LDFLAGS += -static
With this config, it can generate most of demos, but some
failed because of the errors such as ¡°no reference to ¡®hypot¡¯ ¡°,
¡°no reference to ¡®rint¡¯¡± and ¡°no reference to ¡®expft¡¯¡±, and the
generated demos also can run pretty well.
Thought the final size of libs generated by makeing microwin
with uclibc(in my view) is different from that with stdlib, I still have
some doubt about whether it is a correct method to totally switchover
stdlib for uclibc.
Would anybody give a hint whether I do have the microwindows
totally reference to uclibc instead of stdlibc?
If u have not do any research on microwin, maybe u also give me
some hints how to totally compile a hello.c using uclibc instead of
stdlib :-)
Thanks in advance.
Best regards,
