BLAT installtation problem

[ymwur]

Hi,

I am trying to install BLAT. But I encounter a probelm I cannot find solution online.
I got a error message like below:
make[1]: Entering directory `/home/joinet/software/blatSrc/blat'
gcc -O -g -Wall -Wformat -Wimplicit -Wreturn-type -Wuninitialized -o /home/joinet/bin/x86_64/blat blat.o ../lib/x86_64/jkOwnLib.a ../lib/x86_64/jkweb.a -pthread -lpng -lm
/usr/bin/ld: cannot find -lpng
collect2: ld 回傳 1
make[1]: *** [blat] Error 1
make[1]: Leaving directory `/home/joinet/software/blatSrc/blat'
make: *** [all] Error 2

Do anyone tell me how can I fix this probelm?
Thanks.

You have not said what operating system you are installing blat on (is this cygwin on windows) but I am going to guess that the "-lpng" is referring to this library http://swapped.cc/#!/lpng. You can find the download link at the bottom of the page.

Hi

Thank you for information.
I am installing BLAT in 64-bit linux system with Ubuntu 12.
Does lpng also work in linux or is there a similar library for linux?

[GenoMax]

For ubuntu you can install the "libpng" package. https://launchpad.net/ubuntu/precise/+source/libpng

You should be able to use the package manager or do the apt-get install.

I downloaded the libpng and installed it under /usr/local.
But when I install the BlatSrc and the same error message showed up.
I think the error occured wheh it try to run the makefile in the blat folder.
But when I looked this makefile, I could not fine any text spefiying -lpng.

What can be the problem?
Thanks,

Be sure to install the corresponding header files, e.g. for libpng12 -> libpng12-dev

The author of Blat, JIm Knet, just made a updated common.mk file under the inc folder. The new common.mk gets rid of the ependency on libpng. So, now I can install Blat without install libpng. I believe Jim will put the update version in his website soon.
Thank you for all your help.

I'm having the same problem. I can't find the file common.mk on Jim Kent's webpage. Perhaps you could find it again and post the link?

Thanks

My apologies I posted the previous post a bit hastily. I found the common.mk file and altered it as described here http://defsci.blogspot.com/2011/02/c...untu-1004.html

But when I ran make again I get this error again:

make[1]: *** [blat] Error 1
make[1]: Leaving directory `/home/Downloads/blatSrc/blat'
make: *** [all] Error 2

However, the make function ran longer than it ever has!

I'm using ubuntu 64 bit

any ideas?

Have you tried "make clean" followed by another try at "make" with the new common.mk file in place?
