[Rcpp-devel] problems with rInside in Ubuntu
There may well be an error on your end: What made you think it would work with static libraries? Dynamic linking all the way.
Sure, there is an error somewhere. I am just trying to find it and the only way I know how to do it is trying to exclude all the possibilities which are not under my control or which are beyond my current understanding. I believe this is a quite natural process for someone trying to learn a new tool.
"distributed LibRInside.a" ? Fist off, you have the capitalization wrong. Second, how am I supposed to know how YOU built this? I ship SOURCES. You control your builds. There
is
no distributed libRInside.a, only sources and a Makefile.
And your "Fist off" is missing an r. If this kind of nonsense were my only problem in trying to use your code then I would be very glad. I did not build libRInside.a, It was build by apt-get or some other tool which called R CMD INSTALL or something like it in my behalf. Again, I do believe other Ubuntu users may have the same problem. As for the other run that you were so generous to provide me, do you mean something as at the end of this message? If you do then it creates two folders, one call libs with contains a library RInside.o and another called lib which contains libraries libRInside.a and libRInside.o. In other words, the files that you do not distribute are created once we follow your suggestion. Trying to continue to follow your suggestion, I cannot cd to pkg/inst/examples/qt/ as you because there is no such folder pkg in my machine after I follow the steps you suggest (R CMD...) Instead, I can cd to folder examples/qt/ and follow the next step you suggest make clean && qmake && make but it does not work because make: *** No rule to make target `clean'. Stop. I did then what most qt users would do, i.e. open the .pro file in qtcreator. By doing that I get compilation errors due to my using of qt 5.0.1 and are easily fixed, but I still have the linking problem, which I find hard to be caused by the fact that I am using qt 5.0,1, specially because it also happens in a simpler project that does not use qt at all. In resume, by following the steps you suggest I get to a point in which neither me nor you know what is happening and I am trying to figure it out. I am not trying to do anything different or fancy. I am just trying to make things work, and if you could suggest effective ways to achieve this goal I would follow them as carefully as I can. walter. root at linux:/usr/local/lib/R/site-library/RInside# R CMD INSTALL RInside_0.2.10.tar.gz* installing to library ?/usr/local/lib/R/site-library? * installing *source* package ?RInside? ... ** libs /usr/lib/R/bin/Rscript tools/RInsideAutoloads.r > RInsideAutoloads.h /usr/lib/R/bin/Rscript tools/RInsideEnvVars.r > RInsideEnvVars.h g++ -I/usr/share/R/include -DNDEBUG -I. -I../inst/include/ -I"/usr/local/lib/R/site-library/Rcpp/include" -fpic -O3 -pipe -g -c MemBuf.cpp -o MemBuf.o g++ -I/usr/share/R/include -DNDEBUG -I. -I../inst/include/ -I"/usr/local/lib/R/site-library/Rcpp/include" -fpic -O3 -pipe -g -c RInside.cpp -o RInside.o g++ -shared -o RInside.so MemBuf.o RInside.o -L/usr/local/lib/R/site-library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/local/lib/R/site-library/Rcpp/lib -L/usr/lib/R/lib -lR g++ -o libRInside.so MemBuf.o RInside.o -shared `/usr/lib/R/bin/Rscript -e "Rcpp:::LdFlags()"` -L/usr/lib/R/lib -lR ar qc libRInside.a MemBuf.o RInside.o cp libRInside.so ../inst/lib cp libRInside.a ../inst/lib rm libRInside.so libRInside.a installing to /usr/local/lib/R/site-library/RInside/libs ** R ** inst ** preparing package for lazy loading ** help *** installing help indices ** building package indices ** testing if installed package can be loaded * DONE (RInside) root at linux:/usr/local/lib/R/site-library/RInside# ls DESCRIPTION examples help html include INDEX lib libs Meta NAMESPACE NEWS.Rd R RInside_0.2.10.tar.gz THANKS
