c - gromacs compilation gives undefined reference error -

-

i use gromacs on open suse 12.3 platform having trouble it. when trying compile analyzing tool using gmx_template first got error:

g++  -l/usr/local/gromacs/lib   -o msd msd.o -lmd -lgmx -lfftw3f -lxml2  -lnsl             -lm                                                                                                     /usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld:     /usr/local   /gromacs/lib/libgmx.a(pthreads.c.o): undefined reference symbol         'pthread_getaffinity_np@@glibc_2.3.4'                                                                                                                                                                        /usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: note:     'pthread_getaffinity_np@@glibc_2.3.4' defined in dso /lib64/libpthread.so.0 try     adding linker command     line                                                                                                                                                          /lib64/libpthread.so.0: not read symbols: invalid     operation                                                                                                                  collect2: error: ld returned 1 exit     status                                                                                                                                         make: *** [msd] fehler 1

then added /lib64/libpthread.so.0 -l options in makefile

but lot of errors this:

/usr/local/gromacs/lib/libgmx.a(pbc.c.o): in function `put_atoms_in_box_omp._omp_fn.0': pbc.c:(.text+0x862f): undefined reference `omp_get_num_threads'

i think related openmp. not understand enough of building process enable openmp support (probably -fopenmp) , @ same time surprised in case have change cmake files in order make gromacs work. used quick , dirty install following gromacs installation instructions on website.

any suggestions can / did wrong far ? using gcc 4.7

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
