I'm new about RInside and I want to run the examples about QT
I get this error all the time I use "qmake" and "make" as say the README, and I really want to know what can I do about it.
$ g++ -Wl,-O1 -o qtdensity qtdensity.o main.o moc_qtdensity.o -L/usr/lib/i386-linux-gnu -Wl,--export-dynamic -fopenmp -L/usr/lib/R/lib -lR -lpcre -llzma -lbz2 -lrt -ldl -lm -lblas -llapack -L/home/user/R/i686-pc-linux-gnu-library/3.1/RInside/lib -lRInside -Wl,-rpath,/home/user/R/i686-pc-linux-gnu-library/3.1/RInside/lib -lQtSvg -lQtGui -lQtCore -lpthread
/usr/bin/ld: cannot find -llzma
collect2: ld devolvió el estado de salida 1
make: *** [qtdensity] Error 1
I thought it was because I had not the library lzma, but I intalled it and I still get the same error.
What can I do? Can you help me please?

I am trying to build 32bit application on 64bit Debian 7 and something goes wrong:

I installed Google perftools (google-perftools 1.7-1ubuntu1), and add -lprofiler to PKG_LIBS in R, when compiling the C++ code.
library(RcppArmadillo)
library(Rcpp)
Sys.setenv("PKG_CXXFLAGS"="-fopenmp")
Sys.setenv("PKG_LIBS"="-fopenmp -lprofiler")
sourceCpp('my.cpp')
The output is:
/usr/bin/ld: cannot find -lprofiler

Even if I run g++ in bash, I get the same error

I wonder why -lprofiler doesn't specify google perfotools? How can I solve the problem? Thanks!
My g++ is g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3.
Quick ones:
Do you actually have the package libgoogle-perftools-dev installed? Ie do you have shared and static libraries /usr/lib/libprofiler.* ? This is the mother of all development FAQs: you need package libfoo to run code against foo, and package libfoo-dev to compile against foo.
I have old working examples in the slides from my 'HPC with R' talks from a few years ago; those should all work as is.
when I open a terminal, switch to my project directory (which is in my home folder) and run the command "wmake" I get the error:

This error occured the first time today, yesterday everything compiled fine for me.
How can I fix this?
I just installed manually apr and apr_util so i can install activemq c++ library.
When i try to make the cpp library i get the following error:
**

**
and expat is within apr-util and not being linked. how can i update the ld path so that make or environment will find it?
or in short: how can i resolve this?
Usually you'll need to manually specify the library path using -L option.
It would look like ld filename -Lpath -llibname in a single ld operation. Or in this case you may need to add the paths of your library(apr-util here) to the constant of library paths in a Makefile.

Thanks in advance
If libUpTools uses functions lib libresolv, you need to say so:
libUpTools_la_LIBADD = -lresolv (of course -lresolv may be replaced by variables determined by configure etc.)
That way, -lresolv will end up in the .la file and also in the .so file (if you chose to build it) that you can run ldd on for verification.
