Re: [Gretl-devel] [Gretl-users] troubles with shared libraries under cygwin

Ok sorry. switching to gretl-dev for this. history of the discussion added. I have no more informations this morning i will looking for libtool issues. 2010/6/17 Riccardo (Jack) Lucchetti <r.lucchetti(a)univpm.it&gt;: Hello Allin, I found some clues of what is going on when linking the shared librairies . I added a -debug into the libtool command line and get back what it is doing (log joined). So i got the libraries he used to try its link : + deplibs='/usr/lib/libgmp.dll.a /usr/lib/libiconv.dll.a /usr/lib/libintl.dll.a /usr/lib/libpcre.dll.a /usr/lib/libglib-2.0.dll.a -lz /usr/lib/libxml2.dll.a -ldl -lgfortran /usr/lib/libblas.dll.a /usr/lib/liblapack.dll.a -L/usr/lib -L/usr/lib ' When i link manualy a module it work only if add libgretl-1.0.a or libgretl-1.0.so, you can try for example : $ g++ ./.libs/arbond.o /usr/lib/libgmp.dll.a /usr/lib/libiconv.dll.a /usr/lib/libintl.dll.a /usr/lib/libpcre.dll.a /usr/lib/libglib-2.0.dll.a -lz /usr/lib/libxml2.dll.a -ldl -lgfortran /usr/lib/libblas.dll.a /usr/lib/liblapack.dll.a -L/usr/lib ../lib/libgretl-1.0.so -L/usr/lib -shared -o test.so And libtool say what the problem is to us : *** Warning: This system can not link to static lib archive ../lib/libgretl-1.0.la. *** I have the capability to make that library automatically link in when *** you link to this library. But I can only do this if you have a *** shared version of the library, which you do not appear to have. *** But as you try to build a module library, libtool will still create *** a static module, that should work as long as the dlopening application *** is linked with the -dlopen flag to resolve symbols at runtime. So he said that the module should be linked with libgretl-1.0 in shared version !!! But there are the same problem with libgretl-1.0 (undefined symbol) so i build myself with my hands libgretl-1.0.dll (with the same arguments sent to libtool): g++ adf_kpss.o bhhh_max.o bootstrap.o boxplots.o calendar.o compare.o compat.o csvdata.o dataio.o dataset.o dbread.o dbwrite.o describe.o discrete.o estimate.o flow_control.o forecast.o geneval.o genfuncs.o genlex.o genmain.o gensyntax.o gmm.o graphing.o gretl_bfgs.o gretl_bundle.o gretl_commands.o gretl_errors.o gretl_fft.o gretl_foreign.o gretl_func.o gretl_intl.o gretl_list.o gretl_matrix.o gretl_model.o gretl_panel.o gretl_paths.o gretl_prn.o gretl_restrict.o gretl_scalar.o gretl_string_table.o gretl_untar.o gretl_utils.o gretl_www.o gretl_xml.o interact.o kalman.o libset.o matrix_extra.o missing.o modelprint.o monte_carlo.o nls.o nonparam.o objstack.o options.o plotspec.o plugins.o printout.o printscan.o pvalues.o qr_estimate.o random.o strutils.o subsample.o system.o texprint.o transforms.o tsls.o usermat.o var.o varprint.o vartest.o irfboot.o bdtr.o btdtr.o chbevl.o chdtr.o const.o expx2.o fdtr.o gamma.o gdtr.o igam.o igami.o incbet.o incbi.o mtherr.o nbdtr.o ndtr.o ndtri.o pdtr.o polevl.o polrt.o stdtr.o unity.o airy.o hyp2f1.o hyperg.o i0.o i1.o iv.o j0.o j1.o jn.o jv.o k0.o k1.o kn.o psi.o struve.o yn.o kv.o chkder.o dpmpar.o enorm.o fdjac2.o lmder.o lmder1.o lmdif.o lmpar.o qrfac.o qrsolv.o dlog10.o lbfgsb.o -L/usr/lib -llapack -lblas -lgfortran -lm -ldl -lz -lxml2 -lz -liconv -lm -lglib-2.0 -lintl -liconv -lgmp -lfftw3 -lm -shared -o libgretl-1.0.dll Strange it works... so back to the plugins : what the hell !!! I got only : ../libtool --mode=link gcc -module -avoid-version -rpath /usr/lib/gretl-gtk2 -o arbond.la arbond.lo ../lib/libgretl-1.0.la libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin shared libraries ARGH ! There is something tricky with the cygwin version of libtool even with a right order of libraries he always find there are undefined symbols... thanks. 2010/6/16 denis joubert <denis.joubert(a)gmail.com&gt;: - Masquer le texte des messages précédents -
