Android on the transplant ghostscript-9.04 static compiler

Android on the transplant ghostscript-9.04 static compiler

One, description
becauseAndroidnoGlibLibrary, andGCCThe default for dynamic compilation,
in order to enable the program to run on the development board, our ownCProgram needs to use static compiler.
GhostscriptThe download address isHttp://downloads.ghostscript.com/public/. I use theGhostscript-9.04.

Two, online common method
OneGet source code
decompressionGhostscript-9.04.tar.gzAnd will be extracted after theGhostscript-9.04Directory copyGhostscript-9.04-pcandGhostscript-9.04-armTwo
points, respectively, for the compilerPCHost onGSandARM-LinuxTheGS.
Command:
Ghostscript-9.04.tar.gz #tarzxvf
Ghostscript-9.04-pc -R #cpghostscript-9.04
Ghostscript-9.04-arm #mvghostscript-9.04

TwocompilePCHost onGS
Command:
#cdghostscript-9.04-pc/
#./configure
#make
This has been compiled.PCMachine.Gs,Cross compiler at the back of the need to use this step in the compilation
of the intermediate file, in the./obj/aux/Catalog

ThreecompileARM-LinuxTheGS
Configuration environment variable:
In environmental variablesPATHThe path of the cross compiler tool chain(arm-linux-gccPath).
Command:
#exportPATH=$PATH:/toolschain/4.5.1/bin
Start compilation:
Here./configureCommand needs to bePCDifferent host.
Command:
Ghostscript-9.04-arm/ #cd../
#./configure--host=arm-linux
#make
The compilation process will appear the following error
Error occurred:
./obj/devs.tr --include./obj/unix_./obj/aux/echogs-w
Syntax error: word unexpected./obj/aux/echogs:1: (expecting ")"
[obj/devs.tr] make:***errorTwo
Cause of error:
The compilation process requires some intermediate filesEchogs,Genarch,Genconf,Mkromfs)
these files have been compiled here.ARM-LinuxIn thePCSome of the files on the host is not good, so we have toGhostscript-9.04-pc/obj/aux/Copy
come.
Solution method:
takeGhostscript-9.04-pc/obj/aux/Three filesEchogs,Genarch,GenconfCopy
toGhostscript-9.04-arm/obj/aux/
command:
./obj/aux/echogs #cp../ghostscript-9.04-pc/obj/aux/echogs
./obj/aux/genarch #cp../ghostscript-9.04-pc/obj/aux/genarch
./obj/aux/genconf #cp../ghostscript-9.04-pc/obj/aux/genconf
#make

Error occurred:
Syntax error: word unexpected./obj/aux/mkromfs:2: (expecting ")"
[obj/gsromfs1_.c] make:***errorTwo
Solution method:
takeGhostscript-9.04-pc/obj/aux/FileMkromfsCopy toGhostscript-9.04-arm/obj/aux/.
Be carefulMkromfsNeed to update the modification time,Otherwise it will be re created
command:
./obj/aux/mkromfs #cp../ghostscript-9.04-pc/obj/aux/mkromfs
./obj/aux/mkromfs #touch
#make

Compiler is complete, but there is no static compilation, this can not be run under the Android. Is the last link is not used-static.
find./base/unixlink.mak,The last part of this file is used for the last link.
takeFifty-sixthat 's ok
$(ECHOGS_XE) -a $(ldt_tr) -s $(EXTRALIBS) $(STDLIBS) $() $()
Instead
$(ECHOGS_XE) -a $(ldt_tr) -s $(EXTRALIBS) $(STDLIBS) $() $()-Static
command:
No.Rmbin/gs
No./bin/sh<./obj/ldt.tr
Compile successfully, you can download to the development board to try

Three, I am on the transplantGhostscript-9.04Process improvement

Ghostscript-9.04.tar.gz #tarzxvf
Ghostscript-9.04 #cd
#./configure--host=arm-linux
modifyMakefile:
Three hundred and twentyLine: modifySTDLIBS=-lpthread-lmby-lm-static STDLIBS=-lpthread
Three hundred and eighty-sevenLine: modifyCCAUX=arm-linux-gccbyCCAUX=gcc
#make
It is easier than on.

I've been googling for hours but to no avail.

I have successfully compiled ImageMagick on Android via the NDK, but cannot use it to open pdf files because this requires Ghostscript.A lot of ghostscript for android searches has led me to believe ghostscript's android port is MuPdf. Will compiling MuPDF's
NDK source as a dependency for ImageMagick work for me?

There is no port of Ghostscript for Android, we've never done one and I'm not aware of one. MuPDF is a totally different product.

So no, you can't compile MuPDF for Android and expect it to work in place of Ghostscript for ImageMagick.

It should be possible to port GS over to Android, and we would be interested in hearing if you manage that.
