Following my previous note on installing pdf in PlPlot using linux mint 20 64bit.
I have used cmake on libharu-RELEASE_2_3_0 to produce a directory libharu which contains the include and lib directories. I then use cmake on plplot-5.10.0. to produce a directory plplot containing directories bin, include, lib and share. The pdf driver is not installed. During the latter cmake the following cmake.out message is produced: -- Looking for haru pdf header and library -- Looking for haru pdf header and library - not found -- WARNING: Setting PLD_pdf to OFF. I have since amended plplot-5_3.0/cmake/module/Findhpdf.cmake in the following (kludged) fragment: ' ' find_path(hpdf_INCLUDE_DIR hpdf.h PATHS /usr/local/include /usr/include PATH_SUFFIXES hpdf) find_path(hpdf_INCLUDE_DIR hpdf.h PATHS /usr/local/include /usr/include) find_path(hpdf_INCLUDE_DIR hpdf.h PATHS /home/peter/software/libharu/include) if(hpdf_INCLUDE_DIR) find_library(hpdf_LIBRARY NAMES hpdf PATHS /usr/local/lib /usr/lib /home/peter/software/libharu/lib ) ' ' The above cmake.out message is now: -- Looking for haru pdf header and library -- Findhpdf: Found haru header directory, /home/peter/software/libharu/include, and library, /home/peter/software/libharu/lib/libhpdf.so. -- Looking for haru pdf header and library - found -- Checking whether libharu version >= 2.3.0 -- Performing Test LIBHARU_VERSION_LARGE_ENOUGH -- Performing Test LIBHARU_VERSION_LARGE_ENOUGH - Success ' ' DRIVERS_LIST: mem;null;pdf;ps;svg;xfig;xwin DEVICES_LIST: mem;null;pdf;ps;psc;svg;xfig;xwin I now test on a simple plpot program x03.c using gcc -c -I /home/peter/software/plplot/include/plplot x03.c gcc -o x03.exe x03.o -L /home/peter/software/plplot/lib -L /home/peter/software/libharu/lib -lplplot -lcsirocsa -lqsastime -lhpdfs -lm -pthread -lX11 and to my dismay get peter@peter-Akoya-E6237:~/software/Test$ sh x03.sh /usr/bin/ld: /home/peter/software/libharu/lib/libhpdfs.a(hpdf_streams.o): in function `HPDF_Stream_WriteToStreamWithDeflate': hpdf_streams.c:(.text+0x118f): undefined reference to `deflateInit_' /usr/bin/ld: hpdf_streams.c:(.text+0x127a): undefined reference to `deflateEnd' /usr/bin/ld: hpdf_streams.c:(.text+0x129a): undefined reference to `deflate' Can't see these last three functions in libharu-RELEASE_2_3_0/src. Any advice? Best wishes, Peter. On Tue, 28 Jul 2020 at 15:51, Peter Williams <petesweet2...@gmail.com> wrote: > Hello Plplot > I am new to linux (mint 20).
