Article title: skyeye compilation problems and solutions. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
First, let me explain my environment, ubuntu linux 7.04 desktop edition, gcc 4.1.2, and skyeye 1.2.3. Next, download and install skyeye:
1) Download the latest skyeyeon the http://gro.clinux.org, and the latest version is 1.2.3. the downloaded file is skyeye_1_2_3_rel.tar.bz2
2) run the following command to decompress the package:
$ Tar jvxf skyeye_1_2_3_Rel.tar.bz2
3) enter the decompressed Directory
$ Cd skyeye_1_2_3_Rel
4) enter the make command
$ Make NO_DBCT = 1 NO_BFD = 1 NO_ LCD = 1 the following prompt appears:
Test @ ubuntu-kde-pc :~ / Incoming / Skyeye_1_2_3_Rel $ Make NO_DBCT = 1 NO_BFD = 1 NO_ LCD = 1
--------------------------- NOTICE ------------------------------
If You always get error , Please Run " Make NO_CHECK = 1 " Instead .
-----------------------------------------------------------------
Checking whether host is big endian ... No
Checking gcc ... OK ( Gcc version: 4.1 . 2 )

5) Are there any prompts to link to pow? I think pow should be a function in the data computing library. Is it because the math library has no link? Find the SKYEYE_LIB =-Lbinary-larm-ldev-lutils-lbfin-lcoldfire-lmips line of Makefile, add-lm to the end, and then compile. everything is OK.
