Hello, I create my project in the directory ~/project.
And then, I build it in ~/project/build as the following:
cd ~/project
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
make
sudo make install
So far, everything of my program works well.
But, if I delete the files under ~/project/build/*,
My program will come back to the last version.
Why?
Is it possible you're setting your PATH environment variable to
include ~/project/build or something like that so by removing it the
system is falling back on /usr/bin?
Try running "which your_program_name" before and after removing
~/project/build/*.
The cause is that "make install" can't install a lib of my program. But
I don't know
why. Look, it's interesting:
$ pwd
/home/kermit/FreeRecite/build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr ..
..everything is OK!
...[100%] Built target FreeRecite-core
$ sudo make install
[ 84%] Built target FreeReciteCore
[ 92%] Built target FreeReciteUi
[100%] Built target FreeRecite-core
Install the project...
-- Install configuration: ""
-- Installing: /usr/share/FreeRecite
-- Up-to-date: /usr/share/FreeRecite/freeRecite.dict
-- Up-to-date: /usr/share/FreeRecite/freeRecite.mgr
-- Up-to-date: /usr/bin/FreeRecite
-- Installing: /usr/bin/FreeRecite-core
-- Installing: /usr/lib/libFreeReciteCore.so
-- Installing: /usr/lib/libFreeReciteUi.so
Now, everything looks well, run my program:
$ FreeRecite
New Edition of CUI ##If the libFreeReciteUi.so is new,then show it.
New Edition! ##If the programe FreeRecite-core is new, then
show it.
$ sudo rm -rf * ## Delete all the file under the out-compiling
directory "build"
Then run the program again:
$ FreeRecite
## It haven't shown the New Edition of CUI
New Edition! ## Juse the FreeRecite-core is new.
But when I use the command :
$ ls -l /usr/lib/libFreeRecite*
-rw-r--r-- 1 root root 166504 2009-01-19 16:12 /usr/lib/libFreeReciteCore.so
-rw-r--r-- 1 root root 70463 2009-01-19 16:12 /usr/lib/libFreeReciteUi.so
It shows that the two libs are created right now.
Besides, I had remove the lib under /usr/lib/libFreeReciteCore.so by
hand, and
mv the new one to instead of it. The result is also shows the last edition.
What's wrong?
