fortran to c translator

Recently, an error occurred while compiling EGSnrc with gfortran, so I want to use g77 to compile it. I believe that many people who want to compile a large number of old fortran code have the same requirements. After all, gfortan cannot completely replace g77. Many codes that can be compiled with g77 always have various problems in gfortran compilation. GNU explained that they had to give up the upgrade because they could not find enough volunteers t

The main C language compiler in Linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Major C language compilers in Linux 1. GCC The famous gnu c/C ++/Obj-C compiler. The current version is 2.8.1, but is said to be compatible with 2.7.x. The most widely used is the gcc 2.7.2 series. For example, the RedHat5 contains gcc 2.7.2.3. Sometimes there are some problems when using gcc on Cyrix, so there is a set of gcc 2.7.2.3 for Cyrix featu

The following is a summary of settings that Y has recently made when using mpi for Parallel Computing of a program. Because intelfortran (on intelcpu) is efficient, you want to configure intelfortran for parallel computing, record backup here ...... For more information about mpi, see the introduction. The master node is the computer that controls other nodes for computation. we name it node0. The slave node slavenode is the compute node named node1. The following is a summary of the settings th

decompositional approach to matrix computations.] In 1951, Alston householder of the National Laboratory of Alstom Oak Ridge proposed the decomposition method of matrix computing. This algorithm proves that any matrix can be divided into triangles, diagonal pairs, orthogonal pairs, and other special forms of matrices,The significance of this algorithm makes it possible to develop flexible matrix computing software packages.

Example 6: # Include # Include Struct on_disk{/* Int32_t */Long Foo;};Int main (){File * file;Struct on_disk data;# Ifdef writeFile = fopen ("test", "W ");Data. Foo = 65535;Fwrite ( Data, sizeof (struct on_disk), 1, file );# ElseFile = fopen ("test", "R ");Fread ( Data, sizeof (struct on_disk), 1, file );Printf ("data: % LD/N", Data. Foo );# EndifFclose (File );}　Let's take a look at Example 6. Ideally, this program runs properly on both the 32-bit and 64-bit platforms and can read the data

, approximately equal to 2.718 (Java a more precise double value in the form of MATH.E). It is used in an exponential expression like "1.39xe-47", meaning "1.39x2.718-47". However, since the invention of the Fortran language, people naturally feel that E represents "more than 10 less power". This is odd, because Fortran was originally oriented to the field of science and engineering design. Of course, its d

parameter "-R" or "--no-builtin-rules" option to cancel all pre-set implied rules.Of course, even if we specify the "-r" parameter, some implied rules will take effect, since there are many implied rules that are defined using the "suffix rule", so long as there is a "suffix list" in the implied rule (and a system is defined on the target.) suffixes), then the implied rules will take effect. The default list of suffixes is:. Out,. A,. LN,. O,. C,. CC,. C,. P,. F,. F,. R,. Y,. L,. S,. S,. MoD,.

function. This information is useful if you want to improve your program's performance.In order to use GPROF on your program, you must add the-PG option when compiling the program. This causes the program to produce a file called gmon.out each time it is executed. Gprof Use this file to generate profiling information.After you run your program and generate a Gmon.out file, you can get profiling information using the following command:GprofParameter program_name is the name of the program that p

As a famous finite element software, Marc has a very strong non-linear computing power, and MSC has changed its interface after MARC2010, on the one hand, it expands its function, on the other hand, it changes the style of Marc's classic interface, and it has the feeling of returning to modern when using the new interface. Marc has such a wide range of users, in addition to its own powerful, its two development interface is also quite a lot. Compared with the Abaqus's implicit computing

If you have code written in FORTRAN or Pascal that needs to be rewritten in C, f2c and p2c are very useful to you. the C code generated by these two programs can be directly compiled by GCC without modification. If the
