Hi, all: I installed boost by using *./bootstrap.sh* *./b2 install --prefix=/usr* However, I missed two files,* patchlevel.h* and *bzlib.h*: So, afterwards, I have the following two packages installed: *libbz2-dev*and * libpython3.3-dev* . I would like to have a full boost_1_52_0 re-installed. But now, even if I have the files: *libbz2-dev: /usr/include/bzlib.h* *libpython3.3-dev: /usr/include/python3.3m/patchlevel.h* during the re-installation of boost, it still keeps reporting 2 errors: *fatal error: bzlib.h: No such file or directory* *fatal error: patchlevel.h: No such file or directory* So, any suggestions?
