Hi, I am trying to install boost library on Fedora 5. Here is what I did: [root@localhost boost_1_33_1]# ../boost-jam-3.1.12-1-linuxx86/bjam "-sTOOLS=gcc" install --without-python Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (and if you don't know what ICU is then you probably don't need it). ...found 13313 targets... [root@localhost boost_1_33_1]# and the library is installed in [root@localhost boost-1_33_1]$ pwd /usr/local/include/boost-1_33_1 [root@localhost boost-1_33_1]$ ls boost/ But when I build my problem calling boost, it can't find it: /home/yinglcs/data/base/RectUtils.h:11:33: error: boost/lambda/bind.hpp: No such file or directory /home/yinglcs/data/base/RectUtils.h:12:35: error: boost/lambda/lambda.hpp: No such file or directory I appreciate if anyone can help. Thank you. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
