Dear All, I'm supposed to obtain the X11 library in the cygwin setup and all the related binaries under the X11 folder during the configuration from cygwin download terminal. BUt I never get X11.dll or X11.a files after download and installation.
Actually this X11 dependecy arises when I try to compile the Petsc library I don't know where Petsc uses X11 libraries but requires it during compilation. If it'S not provided then the following errors are are reported Your help will be appreciated, undefined reference to `XSetForeground' /cygdrive/d/TEST_FOLDER_asus/petsc-3.4.2/src/sys/classes/draw/impls/x/xops.c:94: undefined reference to `XDrawPoint' ..\..\..\..\petsc-3.4.2\arch-mswin-c-debug\lib\libpetsc.a(xops.c.o): In function `PetscDrawPointPixel_X': /cygdrive/d/TEST_FOLDER_asus/petsc-3.4.2/src/sys/classes/draw/impls/x/xops.c:107: undefined reference to `XSetForeground' /cygdrive/d/TEST_FOLDER_asus/petsc-3.4.2/src/sys/classes/draw/impls/x/xops.c:108: undefined reference to `XDrawPoint' ..\..\..\..\petsc-3.4.2\arch-mswin-c-debug\lib\libpetsc.a(xops.c.o): In function `PetscDrawRectangle_X': /cygdrive/d/TEST_FOLDER_asus/petsc-3.4.2/src/sys/classes/draw/impls/x/xops.c:120: undefined reference to `XSetForeground' /cygdrive/d/TEST_FOLDER_asus/petsc-3.4.2/src/sys/classes/draw/impls/x/xops.c:125: undefined reference to `XFillRectangle'
