Note that the thread library support and -- no-cups options must be added when porting QTE. Otherwise, the header file cannot be found and compilation errors will occur. The complete configuration command is:. /Configure-no-SQL-IBASE-no-SQL-mysql-no-SQL-ODBC-no-SQL-Psql-no-SQL-SQLite-little-Endian-embedded MIPS- depths 8, 16,, 32-qvfb -- no-cups-no-ipv6-no-largefile-ThreadOther options can be added or deleted as appropriate.
Konqueror cannot be compiled into a static library by adding "-- enable-static -- disable-shared". Otherwise, a link error occurs. According to a developer in the email list, this is a bug, however, it is not planned to be solved in the near future. Related patch downloads are available on the Internet.
During configuration, the zlib library is not new enough, but it is strange that I downloaded the latest zlib and compiled and installed it. By tracking the configure script and config. log information shows that it builds a program in the memory, the program calls the relevant functions of zlib, and verifies whether zlib can be linked by checking whether there is an error. The problem was finally found that the cross compiler could not link to the zlib library. It is strange to add the-I-l parameter, set LD_LIBRARY_PATH, and edit LD through the GCC command. so. conf, copy the library to/lib, and/usr/lib won't work. Finally, you have to copy the so file to the Lib path of the compiler to complete configuration and compilation. This problem is hard to understand!
When you copy the compiled/usr/local/konquerore folder and the files under it to the target board, run the MIPs-Linux-Konqueror-qws command under bin. the following error occurs :. /MIPS-Linux-Konqueror: Error while loading shared libraries: libkonqe. so.0: cannot open shared objy. This error has been plagued by me for more than two days. Later, it was solved by huzj's reminder. The reason is that the Konqueror database is not added to the database search path. Run:Export LD_LIBRARY_PATH =/path/of/Konqueror/lib: $ LD_LIBRARY_PATHThen run the Konqueror binary file again.

Appendix: zlib cross-compilation process:
1. Download libz, URL: http://www.zlib.net/

Make ldshared = "mipsel-Linux-GNU-gcc-shared-wl,-soname, libz. so.1 "cc_for_build =" mipsel-Linux-GNU-GCC "cc =" mipsel-Linux-GNU-GCC "LD =" mipsel-Linux-GNU-LD "CPP =" arm- linux-G ++-e "Ar =" mipsel-Linux-GNU-ar RC "prefix ="/opt/nxlinux/GCC/gcc-3.3.4-glibc-2.3.2 "cflags ="-FPIC "libz. so.1.2.3 libz.

If you put the compiled library under another path, you need to add the relevant header file (zconf. h zlib. h) to the related include file.
